ICSE Class 10 Answered
In block and tackle system the mechanical advantage increases with the increase of number of pulleys. GIVE REASON

Expert Answer
If the total number of pulleys used in both block and tackle is n and the effort is applied in downward direction,
then the tension T in nsegments of rope supports the load.
Hence Load W = n×T and Effort E = T
Mechanical advantage = M.A. = Load / Effort = W/E = (n×T) / T = n
where n is number of pulleys.
In figure, tension T in five segments of rope supports load W.
Hence, W = 5 T , Effort E = T and Mechanical advantage M.A. = W/E = (5 T ) / T = 5
