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

Question : 50 of 76

Marks: +1, -0

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

Solution:

Here, the tension in the four segments of the string supports the load

{\L}

∴ \;\; {\L}\;=4 {\T} \;\text " and "\; {\E}= {\T}

∵ \;\; \;\text " M. A. "\;\;=\;{ {\L}}/{ {\E}}

\;=\;{4 {\T}}/{ {\T}}=4
