Question

True or False: A lever that provides an easier effort force cannot, at the same time, also shorten your distance.

Justify why

Answer 1

Hello!

Here is the answer along with the reason!

ANS: TRUE A lever provides an easier effort force but cannot shorten the length at the same time

Reason

What the question really comes down to is torque. If you see the formula for torque, it is given as

where T = torque generated

F = effort or force given to the lever

and d is the length of lever.

From this it becomes evident that, there is a trade off between force supplied and length of lever.

So, for less effort force applied, its wise to have a long lever. This is done to minimize the users's force and considerable amounts of energy.

Hope this helped, Please leave a thumbs up :)
