A block and tackle system of pulleys has velocity ratio 4.
(i) Draw a neat, labelled diagram of the system indicating clearly the points of application and direction of load and effort.
(ii) What will be it's V.R. if the weight of the movable block is doubled?

Answer
(i) Labelled diagram of the system with direction and points of application of load and effort marked is shown below:
(ii) Increase in weight of movable block does not affect velocity ratio. Therefore, V.R. = 4.
