Question

In Figure drawn, a tackle is used to lift the load by applying the force in the downward direction. If the load is raised by $1m$, through what distance will be the effort move?

• A. $5m$
• B. $1m$
• C. $3m$
• D. $4m$

Answer 1

The correct option is A $5m$

As we know that in "$n$" pulley system if effort is moved by a distance "$d$" then load will move by "$\frac{d}{n}$"
hence here load is move by $\frac{1}{n}$ so effort will move by "$1$"
where "$n$"=$5$
hence by taking ratio of effort by load we get $\frac{1}{1/5}$
so effort will move by "5 meter"
