Sample questions
-
1.A fixed pulley is driven by a 100 kg mass falling at a rate of 8.0 m in 4.0 s. It lifts a load of 75.0 kgf. Calculate : (a) the power input to the pulley taking the force of gravity on 1 kg as 10 N. (b) the efficiency of the pulley, and (c) the height to which the load is raised in 4.0 s.
-
2.In the diagram shown below, the velocity ratio of the arrangement is
- a.1
- b.2
- c.3
- d.0
-
3.In a block and tackle system consisting of 3 pulleys, a load of 75 kgf is raised with an effort of 25 kgf. Find : (i) the mechanical advantage, (ii) the velocity ratio, and (iii) the efficiency.
-
4.Which of the following correctly expresses the mechanical advantage of a lever?
- A.Mechanical advantage = Load arm / Effort arm
- B.Mechanical advantage = Effort arm / Load arm
- C.Mechanical advantage = Effort × Load arm
