The "turning effect of a force" (T = F * r) is:

(a) determined as the product of force and the moment of inertia.

(b) generated by concentric forces.

(c) equivalent to the angular momentum.

(d) determined as a product of torque and moment arm.

(e) called "moment" or "torque".

b and e

Explanation:

r x F is the formula for torque.

The "turning effect" or torque happens when concentric forces rotate an object along said center.

a) False because T = Fr = Ia (a = angular acceleration)

b) True

c) False. L = Iw (w = angular velocity), which does not equal Ia

d) False. It is torque, not the product of torque and something else

e) True.
