2. A 400-N weight is supported by a uniform beam with a mass of 30-kg and a length of 1.6 meters. The beam is connected to a wall through a hinged connection at point C as shown below. If the system is in static equilibrium, draw a free-body diagram and determine; a. The applied tension. b. The reaction forces at the hinge (Rx and Ry).

In Fig. 12-33, one end of a uniform beam of mass $40.0 \mathrm{~kg}$ is hinged to a wall; the other end is supported by a wire that makes angles $\theta=30.0^{\circ}$ with both wall and beam. Find (a) the tension in the wire and the (b) magnitude and (c) angle from the horizontal of the force of the hinge on the beam.
4. A 6.00 m uniform beam of mass 17.0 kg is hinged to a vertical wall. The beam is kept in a stationary horizontal position by an 8.00 m cable. One end of the cable is attached to the other end of the beam while the other end of the cable connects to the vertical wall 4.00 m above the hinge. When a 10.0 kg crate is placed on the beam 5.00 m from the vertical wall the system is in equilibrium. SHOW ALL WORK (a) Draw a free-body diagram showing the forces present. (5 points) (b) What is the tension in the cable? (10 points) (c) Compute the magnitude of the horizontal and vertical components of the reaction force on the beam from the wall. (10 points)
