Question

A pulley which has a mechanical advantage 6 and velocity ratio 5
Draw diagram and explain

Answer 1

Answer:A pulley system has a velocity ratio 5.

Explanation:Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram. (i) (ii) Question 6 (a) If the efficiency of the system is 80% find its mechanical advantage. If a load of 10 kgf is pulled up by a distance of 2 m in 10 s, calculate the power developed by the effort (given g = 10 m s-2).
