A uniform horiztonal beam is attached to a veritcal wall by a frictionless hinge and supported from below at an angle theta = 39 degrees by a brace that is attached to a pin. The bean has a weight of 340 N. Three additional forces keep the beam in equilibrium. The brace applies a force P to the right end of the beam that is directed upward an the angle theta with respect tothe horiztonal. The hinge applies a force to the left end of the beam that has a horizontal component H and a vertical component V. Find the magnitudes of these three forces.
