Question
Answer the following in short.
Using a suitable example, describe how a machine acts as a force multiplier.
Solution
It is very difficult to open the sealed metal cap of a cold drink bottle with our bare hands. A simple machine like a bottle opener (Class II lever) multiplies the applied force and much less effort is required to open the cap. Hence, it acts as a force multiplier.
