Unformatted text preview: 24. A strut of length L = 3.00 In and mass m = 16.0 kg is held by a cable at an angle of 0 = 30.0&quot; with respect to the horizontal as shown in Figure P824. (a) Sketch a force diagram, indicating all the forces and their place- ment on the strut. (b) Why is the hinge a good place to use for calculating torques? (c) Write the condition for rotational equilibrium symbolically, calculating the torques around the hinge. (d) Use the torque equa- tion to calculate the tension in the cable. (e) Write the x— and y-components of Newton’s second law for equi- librium. (f) Use the force equation to ﬁnd the x— and ...
