Three identical 8.60-kg masses are hung by three identical springs, as shown in the figure. (Figure 1) Each spring has a force constant of 5.90 kN/m and was 11.0 cm long before any masses were attached to it. Make a free-body diagram for the top mass. Draw the vectors starting at the black dot at the center of the top mass.

h L/2 L/4 MR Ms A horizontal rod of length L and mass MR = 2.6 kg is used to hang a sign on a wall. The right end of the rod is attached to the wall by a hinge. A wire having tension T runs from the center of the rod to a place on the wall a distance h above the hinge as shown. The wire makes an angle 0 = 25° with the rod. The sign has mass Ms = 0.867 kg and hangs distance L/4 from the end of the rod. The system is in equilibrium. What is the tension T in the wire that runs between the wall and the rod? T = 60.35 N %3! T = 42.22 N %3D T = 14.08 N O T = 90.54 N T = 30.19 N %3! What is Fy, the vertical component of the force that the hinge exerts on the right end of the rod? A positive answer indicates an upward force and a negative answer indicates a downward force. Hint: Balance torques about an axis through the center of the rod. O Fy = -4.25 N Fy = 4.25 N Fy = -8.51 N Fy = -6.38 N Fy = 8.51 N
