A uniform beam weighing Wa=1200 N is 3.50 m long and is suspended horizontally by two vertical wires at its ends, as shown in the figure below. A small but dense weight with WL = 550 N is placed on the beam 2.00m from one end, as shown in the figure.

a) are the tensions Ta (in cable A) and TB (in cable B) equal?

b) Considering that this beam is in total equilibrium, now write the equation in rotational equilibrium.

c) In the summation below, write the magnitudes of the CW and the CCW around a point on the left end of the beam, i.e., on the side labeled as needed.
