Explanation / Answer
Torque can be defined as: = R x F= RFsin = I Therefore, A sphere isspinning with a constant angular velocity.
Thisgenerates no torque there is no angular acceleration, if theangular velocity is constant. A 1923 N force is applied 52 cmfrom the axis of rotation and is parallel to the leverarm. This generates no trque because the force is parallel to thelever arm. Torque is equal to RFsin, if it is parallel, is 0 or 180, and sin is 0 at these angles. A 291 N force is applied at the axis ofrotation. This generates no torquebecause there is no distance from the axis of rotation. = R xF. In this case, R would be 0. This generates no torquebecause there is no distance from the axis of rotation. = R xF. In this case, R would be 0.
