The diagram below shows a lever in use.

(a) To which class of lever does it belong ? Give one example of this class.
(b) How will the mechanical advantage of lever change if load is shifted towards the fulcrum without changing it's dimensions.

Text Solution

Verified by Experts

(a) The fulcrum F is in between the load and the effort, so it is a class I lever. A pair of pliers is an example of class I lever.
(b) The mechanical advantage of the lever would increase if load is shifted towards the fulcrum without changing its dimensions.
