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

What career fields can I enter into with a degree in Mechanical Engineering? What is the salary range?

What career fields can I enter into with a degree in Mechanical Engineering? What is the salary range?

Chosen Answer:

There’s a wide variety of fields you can get into with a BS in ME, depending on your interests. You can work in any of the fields previously mentioned like automotive engineering, power generation (boiler and turbine design), aerospace or manufacturing. Within those fields you can look for jobs in basic design, quality assurance, project management or even sales.

Salary range will depend on the location and type of job, obviously. On the low end, you may see offers for around ,000 per year. On the high end, in more expensive cities, you can earn up to ,000 per year. There are of course outliers on either end, but this is the typical range.

With an MS you’d be getting a little more money, about ,000 to ,000 per year and would likely be doing similar work. MSMEs are also commonly hired by large companies to do computational work like FEA (Finite Element Analysis) or CFD (Computational Fluid Dynamics). With a PhD, your starting salary would be in the -,000 range and you’d likely be doing R&D or possibly even forensic engineering in any of these areas. Of course the higher salaries that come with advanced degrees come with the disadvantges of more time in school and lost wages (not earning any money while you’re in school).

Hope this helps.

Can one dryclean/ wetclean by oneself the interior of a car?

I’m too broke to go to a proper carwash specialist!

Chosen Answer:

It’s no problem. Places like WalMart, Target, and automotive stores sell the detergents with the brushes on the cap that are meant to clean car upholstery and carpets. It’s basically carpet detergent in a special bottle. After you apply the detergent and do a second or third pass with clean water, you wet vacuum, and you’re finished

Why are there so many inadequate, green lifestyle solutions aimed at the consumer lately?

Wouldn’t limiting the vast amount of industrial and/or automotive – related pollution that is generated on a daily basis have a far greater impact than anything that any one person could possibly do? This sounds to me like the concept of recycling – companies still manufacture almost everything out of cardboard and plastic without fail which almost always winds up in the trash rather than in recycling boxes – and even if it is in a recycling box, many refuse/disposal companies appear to handle it in the same way as garbage… It makes more sense to make change at the source rather than trying to make some kind of small impact at the consumer-level… If the various existing environmental groups truly care about their planet, I am quite sure that they could enact laws that would have a far greater impact than these inadequate solutions… I challenge these groups to work more assertively on enacting proper legislature to make the effective changes that are required.

Be careful what you ask for. You may just get it.

Updates in Engine Repair in Tampa in Engine

Thirty years ago, the average life span of an automotive engine was about 5 – 7 years. Now the situation is entirely different.

While most engines before develop several problems such as loss of compression, oil pressure, and power, as well as increased emissions, internal noise, and oil consumption after an average of 60,000 to 80,000 miles, engines nowadays have been developed to decrease fuel wash down dilemmas and oil dilution in the crankcase.

Nonetheless, that is not to say that there is no need for engine repair in the roads of Tampa today. Frankly, engine repair is an auto service that certainly won’t be passé in any auto repair shop in Tampa. It may be true that today’s engine technology have extended the life of an engine to such extent that the need for various auto service has been reduced. Nevertheless, these new engines of today will get old and will need engine repair sooner or later.

As a car owner, you need to make a decision when faced with a major engine repair scenario: do you replace the engine or have it rebuilt? Choosing the former will lead you to answer question. That is , are you replacing your engine with a new, remanufactured, or used one?

Obviously, a new engine is very expensive. And if you are on a tight budget, you may opt to just choose between a remanufactured engine or a used one. Do not worry. You are not the only one using remanufactured or used engines. These types of engines are still pretty safe to use as long as it has been worked on by credible mechanics from a reliable auto repair shop in Tampa.

The second option is having an engine rebuild. Engine rebuilds in Tampa also cost less than having a total engine replacement.

However, before an engine rebuild takes place, you must first know that your car engine is rebuildable; meaning there is no excessive wearing and serious damage.

Engine rebuild as an auto service requires no state of the art tools and technology. A mechanic from an auto repair shop normally uses automotive hand tools, gauges, torque wrench, and ring expander and compressor. However, there are some machine work that needs to be done for an engine rebuild and you may need to farm it out from the nearest auto repair shop.

When it comes to buying engine parts, it will save you more money if you go for an engine kit rather that individual packages. Aside from these extra dollars in your savings account, going for a whole engine parts kit reduces your chance of mismatching parts that can ultimately cause major auto service problems. Parts present in the kit include bearings, camshaft, rings, timing chain and gear set, gaskets, valve seals, oil pump, pistons, and lifters.

Engine rebuild costs differently depending on the auto repair shop who does the work. You may opt to choose the one offering auto service at lesser price. However, make sure you do not compromise quality over one’s price. Also remember that the best auto repair shop in Tampa is the one offering good warranty services. As they say: warranty is your guarantee for the quality.

EDIT: You’re absolutely right about the craftsmanship, propreno. I had to put a beam in the bell tower of a church that was about 125 years old. You couldn’t fit a piece of paper between the rafters and the ridge. All cut with hand saws. It was amazing.
