Question 6(i)

A block and tackle system of pulleys has velocity ratio 4.

(a) Draw a labelled diagram of the system indicating clearly, the direction of the load and the effort.

(b) What is the value of the mechanical advantage of the given pulley system if it is an ideal pulley system?

Answer

(a) Labelled diagram of the block and tackle system of pulleys with velocity ratio 4 is shown below:

A block and tackle system of pulleys has velocity ratio 4. Draw a labelled diagram of the system indicating clearly, the direction of the load and the effort. What is the value of the mechanical advantage of the given pulley system if it is an ideal pulley system? ICSE 2023 Physics Solved Question Paper.

(b) The load is being supported by five segments of the string. Therefore, L = 5T and E = T

∴ M.A. = loadeffort\dfrac{\text{load}}{\text{effort}} = 5TT\dfrac{5\text{T}}{\text{T}} = 5
