Question

watch is torque and moment of inertia and radius of gyration​

Answer 1

1. Torque is the force applied to turn a distance r

Torque = f ( force)× r (radius)

2. Moment of inertia( I) is the mass of extended bodies that oppose motion

I = MR ² ( M: mass, R: radius)

3. Radius of gyration (k)

I = MK ²
