Описание: Q3. Can a small force ever exert a greater torque than a larger force? Explain.

Ans. Yes, a small force can exert a greater torque than a larger force, if the small force has a large enough moment arm.

As we know that,
Ʈ = F × d (i)
Eq (i) clearly shows that torque depends on both applied force and moment arm. Moment arm also plays an important role in producing torque. If the moment arm at which small force is acting is greater than the moment arm at which large force is acting, then the torque produced by small force will be greater than the larger force.

For example,
Let F1 = 2N and d1 = 10m Then , Ʈ1 = F1 × d1
Ʈ1 = 2 x 10
Ʈ1 = 20 Nm
And
Let F2 = 5N and d2 = 2m Then, Ʈ2 = F2 × d2
Ʈ2 = 5 × 2
