(13%) Problem 5: A shop sign weighing m;g hangs from one end of a uniform beam weighing mpg. A hinge attaches the
other end of the beam to a wall. The beam has a length of l1. A cable is attached to the beam a distance l2 from the hinge to
help support the beam. The cable makes an angle 0 with the beam as shown.

E A 13% Part (a) On the following free body diagram, draw all of the forces acting on the beam, representing the forces as vectors. Use a coordinate systen
with the x-axis on the horizontal (along the length of the beam) and the y-axis vertical (perpendicular to the beam). Use "wb" for the weight of the beam, "ws"
for the weight of the sign, "FT" for the force of tension, and "H" for the force on the hinge. Finally, since we don't know the angle that the force on the hinge
will act based on the diagram alone, let it be acting at an angle be denoted "o" from the positive y-axis.

4. A packaging machine mechanism has a link with a square cross section of 0.50 in on a side.It is subjected to a load that varies from a tensile force of 750 lb to a compressive force of 130lb. Draw a sketch of the variation of stress versus time, and compute the maximum stress,minimum stress, mean stress, alternating stress, and stress ratio, R.
