A 57.0 kg cheerleader uses an oil-filled hydraulic lift to hold four 130 kg football players at a height of 1.20 m.If her piston is 19.0 cm in diameter, what is thediameter of the football players' piston?
You are designing a hydraulic lift for an automobile garage. It will consist of two oil-filled cylindrical pipes of different diameters. A worker pushes down on a piston at one end, raising the car on a platform at the other end. (See (Figure 1).) To handle a full range of jobs, you must be able to lift cars up to 3000 kg , plus the 400 kg platform on which they are parked. To avoid injury to your workers, the...
Consider the hydraulic jack represented beside. It is filled
with mineral oil (a lubricating liquid). Assume that a person is
able to push the left piston (F1) with a maximum force of 343 N.
The diameter of the piston on the left is only 2 cm and that of the
piston on the right much larger at 40 cm.
• A) If the piston on the right is used to lift a car, what is
the highest car weight (in...
The hydraulic oil in a car lift has a density of 8.17x10^2 kg/m^3. The weight of the input piston is negligible. The radii of the input piston and output plunger are 8.56x10^-3 m and 0.171m, respectively. What input force F is needed to support the 27200-N combined weight of a car and the output plunger, when (a) the bottom surfaces of the piston and plunger are at the same level, and (b) the bottom surface of the output plunger is...
The answer is E
A 12,000-N car is raised using a hydraulic lift, which consists of a U-tube with arms of unequal areas, filled with oil with a density of 800 kg/m^3 and capped at both ends with tight-fitting pistons. The wider arm of the U-tube has a radius of 18.0 cm and the narrower arm has a radius of 5.00 cm. The car rests on the piston on the wider arm of the U-tube. The pistons are initially at...
A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....
