Compute the each part of following question given below:
Question: In a hydraulic lift, the radii of the pistons are 2.86 cm and 9.4 cm. A car weighing W = 9.3 kN is to be lifted by the force of the large piston.
Part I: What force Fa must be applied to the small piston?
Part II: When the small piston is pushed in by 11.6cm, how far is the car lifted?
Part III: Find the mechanical advantage of the lift, which is the ratio W/Fa.
Please keep answer short and simple and please no copy and paste.
