Question

to lift an automobile of 2000kg a hydrolic pump with a large piston 900 cm^2 in area is employed .calculate pump with small piston of area 10 cm^2 to accomplish this task

Answer 1

900 sq cm divided by 10 sq cm = 90 to 1 advantage

2000 kg divided by 90 = 22.2 kg of force on the small piston.

This, of course, does not take into consideration any mechanical advantage that might be realized in the linkage of the operating lever if one is used.

Answer 2

900 sq cm divided by 10 sq cm = 90 to 1 advantage

2000 kg divided by 90 = 22.2 kg of force on the small piston.

This,surely, does not take into consideration any mechanical advantage that might be realized in the linkage of the operating lever if one is used.
