automative lif rasise a 3500lb car 7ft above floor level if the hydraulic cylinder contain 8in diameter piston?

An automotive LIFOtraisese a 3500lb car 7ft above floor level if the hydraulic cylinder contain 8in diameter piston and a 4in diameter rod,determine the
A. work necessary to lift the car
B. required pressure
C. power if the lift raises the car 10 s
D. Descending speed of the lift for a 10-gpm flow rate
E. flow rate for the auto too descend in 10 s

Chosen Answer:

All these answers based on 8 inch lifting cylinder. You haven’t specified anything about the 4 inch rod so haven’t used that in these answers

a). work = force x distance
work = 3500 lb x 7 ft = 24,500 ft-lbs of work
b) 8 inch diameter piston = area of pi * r^2 = 50.26 sq inches
3500 lb / 50.26 in^2 = 69.6 psi pressure
c) power = work / time = 24,500 ft-lbs / 10s = 2450 ft-lb/ second
(one foot-lb /second = 0.738 watt so –> 2450 * .738 = 1,808 watts of power in SI system)
d) volume of a cylinder = pi * radius squared * height
one gallon = 231 cubic inches
10 gallons = 2,310 cubic inches
V =2,310 cubic inches = 3.14 * 4in ^2 * height
height = 2310 / (pi * 16) = 45.96 inches

So 10 gallons a minute will lift car or descend car 45.96 inches or 3.8 feet a minute

e) Flow rate to descend in 10 seconds instead of a minute is 6 times faster (60 sec a minute / 10 sec) = 6.
6 * 10gpm = 60 gpm

Ca Contractor License Bond For The Company in Company

It’s often that a business may be looking to branch out to another state and are wondering what requirements need to be met before that all important first job. Or it could be just that there’s a group of entrepreneurs that are forming a new company and need to learn all the ins and outs from the ground up. Either way, every contracting company should know the CA contractor license bond.

What Is Behind A Bond

A CA contractor license bond is part of the requirements for a company that’s business is constructing buildings on the professional level. These bonds are usually held with a cash deposit that is placed with the stare or a local municipality. There are also companies that offer services to constructing companies with getting the right paperwork and dealing with where to file the forms. There are occasionally even companies that offer payment plans and make it even easier and more achievable for any company, no matter where they are with their business plans, to get going with the right bonds.

Who Has To Get A CA Contractor License Bond

When a company is getting started constructing buildings, often college dorms, apartment buildings, or other similar constructions, it’s vital to have a contractor license bond. What this will mean is getting the right paperwork to the right places, and then get the cash deposit to the right place. The important thing to think about and remember here is that a little research can go a long way. If getting into the area of construction, find out what is needed before attempting to get out there with the business. There’s nothing worse than taking a job and then realizing a company doesn’t have the credentials to follow through with what they have proposed, in this case following up on the accepted bid.

What Purpose Does A bond Serve

The reason a contractor needs to have a CA contractor license bond is to insure the public as to the quality of the buildings they are constructing. What this means is the company must keep up to speed on all the safety regulations and laws that an area enforces. The idea behind these bonds is to protect the public from unsafe buildings being erected all over the place. Having a company that has a license bond tells the public that they keep up on laws of safety and adhere to the laws in regards to constructing a building.

It Is As Easy As It Sounds

This is definitely one those areas where just getting the process initiated can be the most difficult part of the entire process. With this in mind, try getting out there and doing a little research into what is going to get and help keep the company running. Spending a little bit of time this way will go miles into giving a company the right and best start. Getting off on the wrong foot can be the difference between having a long standing company that provides a great living, and not having a company that lasts more than a year.

Alignment is Important Part of Complete Houston Automotive Repair Service in Car

After you have spent money for a high quality foreign car, of course you want the car to perform at the highest possible level. It is the reason you choose your car was for its superior driving experience. In order for to work at their peak, they need to be kept in optimum condition. Maintaining the alignment on your import car is important to keep your everyday driving experience as exciting as the first test drive.

Having the wheels in their proper place is called a wheel alignment and it is an essential part of any Houston complete automotive repair service.

This process adjusts the angles of the wheels so that they are in a perfectly parallel position in relation to each other. It also makes sure that they are exactly perpendicular to the ground. Getting the wheels aligned ensures that the vehicle does not pull to one side or the other. A proper alignment will help the driver enjoy the car more and keep him safer.

Well aligned wheels keep the car moving straight and true. It gives the driver better control and a more relaxed ride. A good alignment job eliminates that loose feeling in the steering that makes so many drivers call their Lexus auto repair shop or other brand specific garage. The way the car handles, especially in poor driving conditions, make a big difference to the driver. Bad alignment makes him work harder to maintain control. Keeping the wheels aligned makes the drive safer and more enjoyable.

A good alignment can help lengthen the life of the tires. When the wheels are slightly off, the tires wear more quickly. More pressure is applied to the wheels when they aren’t aligned so they experience more friction.

Tires for some models can be expensive so this simple European import car repair can save a lot of money. It also saves money by improving gas mileage.

Your car’s wheels can go out of alignment for any number of reasons. Hitting a curb or pot hole are some of the most common mishaps that can throw the wheels off. Failing to properly maintain the car, including the wheels, is another culprit.

To find out if you need this service, start by checking the tires for patterns of uneven wear. You can measure the difference in tread heights by placing a coin in the grooves and comparing the results. If the tread is deeper on one side that the other, you may need an alignment. Also, run your hand over the tread, being careful of exposed steel belt wires and road debris. If it feels smooth in one direction but rough in the other, you need an alignment soon. This “saw tooth” wear pattern indicated rapid tired degradation.

Your technician should begin by checking for worn out front end parts, as repairs may be needed before an alignment can be performed. The best kind of alignment is a four wheel alignment. This allows the technician to adjust and compensate for any problems in one end or the other.

When the work is done, check the job by driving on a straight, flat stretch of road. See if the wheel remains level and steady and be sure the car does not pull to either side. If you’ve chosen a quality Houston import car repair provider, you should see a big difference in the way your car handles.

What is the best editing software for Automotive Photography?

I am researching equipment and editing software for a new position and need to know if there are any easier to learn/use editing software programs for Automotive Photography

Chosen Answer:

There are no programs especially for “automotive photography”.
If you want “easy to use”, then all you’ll have is a toy-level app/software, and that is close to useless.

Unfortunately, if this is a serious job instead of a bit of teenaged fun, then you need a real program such as Photoshop or Gimp. or Elements would probably do, too.

In any case it sounds like a job for someone who knows what they’re doing, or has the time and ability to learn.

Insufficient procurement system to restrict the development of automotive electronics in Vehicle

More different from the foreign operating performance based parts procurement system position, domestic own-brand models due to the low price, own brands is the cost of system control in parts procurement principles-based. A certain level allows companies to focus on parts procurement, product cost, and less emphasis on the quality of the product, makes the quality of own brand products it is difficult and joint ventures or imported models are comparable, and has been to give people low-quality low-cost image.

In fact, a complete parts procurement system is not only on vehicle production play a specific role in more effective optimal control of the vehicle product quality. As we all know  Smoked Toyota Motor Corporation is about 70% of the parts of the implementation of external procurement. It is understood that the Toyota automobile manufacturing from development to production at all stages are completed jointly with the Association of enterprises. Therefore  Smoked today with superior international competitiveness of Toyota and its high-quality automotive products, is also largely benefited from it a strict, scientific and continuous improvement of parts procurement system.

It is worth noting that the complete parts procurement system can play a positive role in R & D and innovation of its own brand vehicles and components enterprises. For example, in the platform of the vehicle development, parts procurement system can promote its own brand a comprehensive positive development system. For some components, OEMs can introduce some parts enterprises to develop. The one hand, and parts enterprises to work together to resolve the relevant parts design issues, on the other hand can also contribute to the development of parts enterprises.

In addition, the auto parts enterprises to smoothly enter the procurement system of the whole plant, to achieve the basic requirements of the OEMs in terms of quality, service, technology and price.

Although China has become the world’s largest auto market, but the auto industry’s point of view, the development of China’s automobile is still quite weak, while the automobile industry to establish a complete parts and auto e-procurement system will also become an inevitable trend.Main products: car dvd player  with good quality.  But the key question we must have in-depth understanding, learn to use and innovation. Thus, by this kind of advanced study and research ways of supporting the production, China’s automobile industry competitiveness and face the challenges in the WTO has an important significance.
