Question

Calculate the net torque about the axle of the wheel shown in the figure.(Figure 1) Assume that a friction torque of 0.60m?N opposes the motion. Assume F1= 26N , F2 = 36N , F3 = 25N .

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

Calculate the net torque about the axle of the wheel shown in the figure.(Figure 1) Assume that a friction torque of 0.60m?N opposes the motion. Assume F1= 26N , F2 = 36N , F3 = 25N . Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

The torque = T1 +T2 + T3

T1 = 26 * 0.24 = 6.24 Nm

T2 = 36 * 0.12 = 4.32 Nm

T3 = 25 * 0.24 = - 6 Nm [ torque is NEGATIVE as a counterclockwise torque ]

T1 + T2 + T3 = 4.56 Nm

The wheel will turn clockwise without friction

Net torque = 4.56 - 0.60 = 3.86 Nm
