Question

what is the magnitude of net torque about the axle? Express your answer to two sign?

Part A

In the figure (Figure 1) , what is the magnitude of net torque about the axle?

Express your answer to two significant figures and include the appropriate units.

Fig-1:

Part B

What is the direction of net torque about the axle?

Counterclockwise?

Clockwise?

Answer 1

This is the Best Answer for what is the magnitude of net torque about the axle? Express your answer to two sign?

0.2Nm

Clockwise

r=0.02 m

Torque = r*30-r*20 ( taking inside the plane +ve direction)

Thus you get the answer 0.2 which is positive hence net torque in clock wise direction.

Applying right hand thumb rule.
