Problem (4) The rod AB is suspended from two rigid cables. When the rod is hanging in th position shown, the forces in the cable are measured to be 6.8 lb at A and 5.2 lb at B. Immediatel after the cable at B is cut, the force in the cable at A is reduced to 3.6 lb. (a) Show that the distance d that locates the mass center G is 6.5 in. (Hint: The rod is at rest before the cable is cut) (b) Determine the angular acceleration of the rod immediately after the cable at B is cut. (Hint: The angular velocity is zero immediately ufter the cut) (c) Determine the mass moment of inertia of the rod about G. 15 in. A В

Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.
