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

Why Use a Boat Lift? in Boat

You may be asking yourself” why should I purchase a boat lift“?  If your home is in Tampa, Clearwater, St Pete, Bradenton or Sarasota and moved here from the north you may be thinking, the water will never freeze here so why should I invest in a boat lift.  The fact the water does not freeze is actually one of the reasons, but we will get to that in a minute.

One of the first reasons to use a boat lift is that someday you will want to sell your boat.  When a potential buyer knows your boat was on a boat lift and not in the water they are inclined to pay more for your boat.  The warm waters of Tampa Bay and Sarasota that never freeze are a great place for marine live to thrive.  The warmer the water the more marine life grows.  If you keep your boat in the water it is a necessity to have bottom paint on your boat.  Putting bottom paint on your boat will definitely hurt the resale value.  So having your boat on a lift increases the boats resale value.  The same can be said for the resale value of your home.  When people are shopping for a new waterfront home in Tampa Bay and Sarasota having a boat lift with the house is a real plus.

Having your boat on a lift and out of the water can help to protect it during a storm.  You do not have to worry about a dock line breaking and your boat being damaged as a result of the boat sitting hitting the dock and pilings.  Needless to say this also protects your investment in your dock during the same potential storm damage.  When wind and current conditions are make it difficult to pickup dock lines off pilings a well designed boat lift can also make it easier to dock your boat while protecting it from being damaged during docking.

Last but not least, having a boat lift makes boat cleanup and engine flushing much easier.  With the boat out of the water and on a lift cleaning the topsides and bottom of your boat is a snap.  Flushing your engine will make it last longer.

Using Hydraulic Scissor Lift Tables in Small-business

Hydraulics system is very powerful system that can apply a huge amount of force in moving an object. That is why in scissor lift tables which is used for lifting heavy objects, hydraulic systems can be applied. Hydraulic scissor lift table is a small equipment and yet a very powerful equipment that could lift extremely heavy objects. It can lift heavier objects compared to the regular scissor lift tables. Since scissor lift tables are small in size, it makes it easier to be stored in any desired location.

Hydraulic Scissor Lift Tables for Lifting Extremely Heavy Objects

Scissor lift tables are so powerful in that it can be used to lift objects such as heavy trucks, machines and other heavy objects that you can think of. Its rods can extend longer compared to other type of scissor lift table.

Hydraulic scissor lifts as elevator

There are times when hydraulic scissor lift tables can be used as elevators. It can be used perfectly when you need to go to different high locations and yet no cost elevators exist. Using hydraulic scissor lift tables are a cheaper compared to the regular elevator. The good thing about hydraulic scissor lifts is that it can be moved from 1 place to another.

Disadvantage of Using Hydraulic Scissor Lift Tables

One major disadvantage of most designs of hydraulic scissor lift tables is that it moves slowly when it is nearly fully extended or when it is nearly contracted to its original position. In between these 2 extremes, hydraulic scissor lift tables move quickly but with inconsistent speed.

Safety checklist

Hydraulic scissor lift tables can be used in different places.

Some are used in construction sites and some are used at the local grocery market. However there are a few certain points that a person should consider when using the hydraulic scissor lifts. A person when using the lift should never overload the machine as it could lead to serious complications

  • Different manufacturers of scissor lift tables have different designs of hydraulic scissor lift tables. Having said that, they also have different instructions on how you can operate it. Before operating scissor lift tables, make sure that you read and understand the instructions on how to operate. This is needed to ensure the safe use of the equipment.
  • Do not overload the scissor lift table. Although hydraulic scissor lift tables are design to lift up heavy objects, it still has limitations. Overloading the equipment can damage the equipment which may cause more casualties when damaged while operating it.
  • Check it before you use it. Make sure that you test if its fully working before you operate it. Doing this can help you maintain your equipment and it also prevents possible casualties that is caused by operating under its damaged condition.

Cosmetic Skin Fillers – Lift Again? in Face

Filling much media coverage lately, appearing everywhere from CNN to new local stations. They are presented as the “new face wash” because they are an alternative to traditional plastic surgery.

But what exactly are these procedures? How they work and what risks do they bring? Let’s take a look at the fillers.

What’s in a name?

Filling get their name because they are used to fill certain areas of the skin (dermis) for cosmetic purposes. Basically, the substances injected into the skin – usually face – to smooth wrinkles and gives the face look younger and richer. In medical circles, this procedure is also called “volumizing face,” which refers to the goal of adding volume to the patient’s face.

Commonly used products

You’ve probably heard of collagen injections lips. Collagen is one of several fillers used for these purposes. Although often associated with improvement of the lips, it can also be used on the face in general.

We have a truly natural collagen layer between the skin and lining of tissues. With advancing age, however, collagen levels decrease, and this leads to the expression “buried” on his face. Cosmetic surgeons can inject collagen products (made from either cow or human donor), in order to increase the volume of the patient’s face. So, “volumizing face.” Term

Restylane (R) and Radiesse (R) are other products that are now commonly used in the United States. The “r” in parentheses is the registered trademark, by the way. Unlike collagen, which is a natural substance, both Restylane and Radiesse are the property of the products. Let’s look at each in more detail.

* Radiesse is a dermal filler used for aesthetic reasons.

The product is designed to smooth facial wrinkles and give the face a fuller, younger. It is manufactured by BioForm Medical, Inc. The FDA approved Radiesse for use in the United States in December 2006. Since then it has become very popular as a product to cover the skin. Like most of the burdens of the skin, the effects of Radiesse are temporary and are said to last up to six months.

* Restylane is manufactured by Q-Med. The FDA approved the product for use in the United States back in 2003. The main ingredient in Restylane is hyaluronic acid. It is also a temporary treatment to reduce wrinkles that are typically used in the nose and mouth.

Thinking and research

Although they can not produce the long-term effects of a facelift, dermal fillers has some obvious advantages. For one thing, non-surgical treatments with very little downtime (compared to a facelift).

That said, there are potential risks associated with these and other “skin filler” products. So if you are considering a cosmetic dermal filler procedure, you owe it to yourself to do a lot of research before making a final decision. Start by locating and comparing the different products that are available these days. Look objective, whenever possible. Visit the FDA and to read the notes on each product approval.

Then, if and when you choose an expert to perform the procedure, be sure to ask lots of questions. To ask how long the doctor has used the product, and that kind of success that they (and their patients) have experienced. Take time to read as much as possible, and make a wise decision.
