If the load is raised by 1m, through what distance will effort move?

Open in App

Solution

Since the load is supported by five strands of the string its velocity ratio is 5.
Also, $V . R . = \frac{distance moved by effort}{distance moved by load}$
$\Rightarrow 5 = \frac{distance moved by effort}{1 m}$
$\Rightarrow$ distance moved by effort $= 5 m$
