Question

When load is pulled up by a distance $1m$, how far does the effort end move?

• A. $1m$.
• B. $4m$.
• C. $6m$.
• D. $2m$.

Answer 1

The correct option is B $4m$.

Here it is a "$4$" pulley system hence if effort will move distance "$d$" then load will move at distance'$\frac{d}{n}$"

where "$n$"$=4$

so by taking there ration we find $\frac{effort}{load}$=$\frac{d}{\frac{d}{n}}$$=4m$
