Write the general mathematical relation that exists between the total (vector) angular momentum L r of a system about a point and the net external (vector) torque τ r acting on the system about the same point. 2. A spinning bicycle wheel of total mass M and radius R is suspended from a rope at point P on its axle, a distance s from the wheel’s center of mass (CM). (a) Write an expression for the magnitude of the torque τ about point P produced by the wheel’s weight (in terms of M and s ). = τ ____________________. What is the direction of this torque τ r as a vector quantity? (b) What torque about point P is produced by the tension force exerted by the rope?...
