The diagram below shows a pulley arrangemnet :
(i) Copy the diagram and mark the direction of tension on each strand of the string.
(ii) What is the velocity ratio of the arrangement ?
(iii) If the tension acting on the string is T, then what is the relationship between T and effort E ?
(iv) If the free end of the string moves through a distance x, find the distance by which the load is raised.

Explanation

(i) The diagram with direction of tension on each strand is shown below.

(ii) Velocity ratio = 2
(iii) E = T
(iv) Load is raised by a distance `x/2`.
