- The rotational form of Newton's 2nd law can be written in terms of the angular momentum as: TP = Tnet dt Select ALL statements below which are true regarding the rotational 2nd law. -avg The change in system angular momentum in a interval of time At is AL=Tnet At where Tnet is the average net torque. O The angular momentum of the system is conserved if there is no net external torque. O By Newton's 3rd law all internal torques cancel so only external torques contribute to the net torque. O The rotational kinetic energy is conserved if there is no net external torque.For F = 51 lb, compute the combined moment of the two forces about (a) point O, (b) point C, (c) point D. The moments are positive if counterclockwise, negative if clockwise.For the shaded area, locate the centroid and calculate the moments of inertia about the given x and y axis.
