Cable L. As shown in the figure, a uniform beam of length L is supported at angle 9 by a horizontal cable and a wall hinge. The tension in the cable is T. In terms of L, O,g. T, and numerical constants, as needed, Cable A) draw forces acting on the beam B) find the gravitational force on the beam in unit-vector notation. C) find the force on the beam from the hinge in unit-vector notation. D) Then, the cable is cut and the beam is no longer in equilibrium. Find the magnitude and direction of the initial angular acceleration of the beam about the hinge?

A traffic light hangs from a pole as shown in (Figure 1). The uniform aluminum pole AB is 8.00 m long and has a mass of 10.0 kg . The mass of the traffic light is 25.0 kg . a)Determine the tension in the horizontal massless cable CD. b)Determine the vertical component of the force exerted by the pivot A on the aluminum pole. c)Determine the horizontal component of the force exerted by the pivot A on the aluminum pole.
