A screw jack, 25% efficient and having a screw pitch 0.4cm is used to raise a load through a certain height. If in the process, the handle turns through a circle of radius 40cm, calculate:
1 velocity ratio of the machine
2 mechanical advantage of the machine
3 effort required to raise a load of 1000N with the machine (take pie = 3.14)?
