The drawing shows a uniform horizontal beam attached to avertical wall by a frictionless hinge and supported from below atan angle θ = 38o by a brace that isattached to a pin. The beam has a weight of 338 N. Three additional forces keep the beam in equilibrium. The brace applies a forceP to the rightend of the beam that is directed upward at the angle with respectto the horizontal. The hinge applies a force to the left end of thebeam that has a horizontal component H and a vertical componentV. Find the magnitudes of these three forces.
