Question 6(ii)

The diagram below shows a block and tackle system.

The diagram shows a block and tackle system. Copy and complete the labelled diagram showing the correct connection of the tackle, the direction of the forces involved to obtain maximum V.R. with the convenient direction. Calculate the M.A. of this pulley system if its efficiency is 80%. ICSE 2024 Specimen Physics Solved Question Paper.

(a) Copy and complete the labelled diagram showing the correct connection of the tackle, the direction of the forces involved to obtain maximum V.R. with the convenient direction.

(b) Calculate the M.A. of this pulley system if its efficiency is 80%.

Answer

(a) The completed diagram is given below:

Draw a diagram to show a block and tackle pulley system having a velocity ratio of 3 marking the direction of load (L), effort (E) and tension (T). ICSE 2024 Specimen Physics Solved Question Paper.

(b) η = 80% given

V.R. = n = 3,

M.A. =?

η = M.A.V.R.\dfrac{\text{M.A.}}{\text{V.R.}}

80100\dfrac{\text{80}}{\text{100}} = M.A.3\dfrac{\text{M.A.}}{\text{3}}

M.A. = 80100\dfrac{\text{80}}{\text{100}} x 3= 240100\dfrac{\text{240}}{\text{100}} = 2.4
