Homework Answers
option a is correct,
because all are of same magnitude and are equal in distance from the pivot point so can produce equal torque
T1=T2=T3=T4

Two forces equal in magnitude and opposite in direction, acting on an object at two different points, form what is called a couple. Two antiparallel forces with equal magnitudes_1 = F_2 =7.90 N are applied to a rod as shown in the figure (Figure1). What should the distance l between the forces be if they are to provide a net torque of 5.20 N m about the left end of the rod? Is the sense of this torque clockwise or...

Four forces of the same magnitude but differing directions act
at and tangent to the rim of a uniform wheel free to spin about its
center of mass(CM).
Which statement about the wheel is correct?
1. The net force on the wheel is not zero but the net torque
about the CM is zero.
2. The net force on the wheel and the net torque on the wheel
about the CM are zero.
3. Neither the net force on the...
