Question

9) If the angle of force application is not perpendicular to an object, the amount of torque produced will A. Increases B. Decreases C. Remains constant D. Is zero E. None of the above 10) Static equilibrium is a special case where A. Both the linear and angular accelerations are unequal B. Both the linear and angular accelerations are equal C. The linear acceleration is greater than angular acceleration D. The angular acceleration is greater than the linear acceleration E. None of the above 11) With respect to torque, why should you teach a physical education class to rotate their arms in the opposite direction of their legs when they are running?

Explanation / Answer

Torque=rFsin(theta)

If theta=90 degree

Torque=rF

If theta is not 90

Torque<rF

So it will decrease

Option (B)

Q10

Option E

Q11

To maintain rotational equilibrium and produce net torque=0
