Question

A catapult has a lever arm of 0.5m and is pulled with a force of 50 N. What is the torque produced?

Answer 1

`25` `N` `m`

Explanation:

To find the torque produce, we make use of the formulae below:

`T=Fr`
Where;
`->` `T` is the torque produced
`->` `F` is the force applied which in this case is `50` `N`
`->` `r` is the radius which in this case is also the lever arm & is `0.5` `m`

Substitute the values given into the formulae. Then we have
`T= 50 xx 0.5`
Hence, `T=25` `N` `m`
The unit of torque is `N` `m`
