## Torque Revision Questions

1) Calculate the net torque for the system shown in the figure (take anticlockwise as positive). What is the net torque of the system if cos 370 = 0.8 and sin 370 = 0.6?

1. 110 N × m
2. 32 N × m
3. - 26 N × m
4. 26 N × m

2) Calculate the net torque of the system shown in the figure. (Take anticlockwise as positive) 1. - 90 N × m
2. 90 N × m
3. - 30 N × m
4. - 18 N × m

3) Rank the torques the four forces in the figure produce in the system (greatest first). 1. τ4 > τ1 > τ2 > τ3
2. τ4 > τ3 > τ1 = τ2
3. τ4 > τ3 > τ1 > τ2
4. τ4 > τ1 > τ3 = τ2
