The drawing shows a uniform horizontal beam attached to a vertical wall by a frictionless hinge and supported from below at an angle Î¸ = 39o by a brace that is attached to a pin. The beam has a weight of 340 N. Three additional forces keep the beam in equilibrium. The brace applies a force to the right end of the beam that is directed upward at the angle Î¸ with respect to the horizontal. The hinge applies a force to the left end of the beam that has a horizontal component and vertical component . Find the magnitudes of these three forces.
