The drum of a lifting device lifts a load of 2 000 N. If the diameter of the drum is 0,4 m, calculate:

a)

The torque exerted by the load on the axle of the drum.

1 answer

To calculate the torque exerted by the load on the axle of the drum, we first need to calculate the force exerted by the load on the drum.

We know that torque (τ) is equal to force (F) times the radius (r) at which the force is applied. Since the diameter of the drum is 0.4 m, the radius (r) is 0.2 m.

Given that the force exerted by the load is 2 000 N, the torque can be calculated as:

Torque = Force x Radius
Torque = 2 000 N x 0.2 m
Torque = 400 Nm

Therefore, the torque exerted by the load on the axle of the drum is 400 Nm.
