Sample questions

1. 1.Calculate the velocity ratio of a pulley system consisting of $n$ movable pulleys and one fixed pulley. What is the velocity ratio (V.R.) of this system?
   • A.V.R. = $n$
   • B.V.R. = $2^n$
   • C.V.R. = $n^2$
   • D.V.R. = $2n$
2. 2.A woman lifts a load of 6 kg using a lever. The force applied by the woman is 70 N. Calculate the mechanical advantage. (Take $g = 10 \, \text{m} \, \text{s}^{-2}$)
3. 3.For the single movable pulley shown in the diagram , which expression correctly calculates the Mechanical Advantage (M.A.)?
   • A.M.A. = T / (2T)
   • B.M.A. = 2T / T
   • C.M.A. = T / T
   • D.M.A. = 2T / 2T
4. 4.A pulley system has 5 pulley in all. Its velocity ratio is :
   • A.less than 5
   • B.more than 5
   • C.5
   • D.none of these
5. 5.What is an ideal machine, and how does it differ from an actual machine?
   • A.An ideal machine has no energy loss, so its work output equals work input and efficiency is 100%, while an actual machine has energy losses, reducing its efficiency below 100%.
   • B.An ideal machine requires more input energy than output energy, while an actual machine converts all input energy into useful work without losses.
   • C.An ideal machine has friction and other losses, making its efficiency less than 100%, while an actual machine operates without any energy loss.
   • D.An ideal machine and an actual machine are the same, both having 100% efficiency and no energy losses in practical use.
