A solid bar of length L = 1.30 m has a mass m1 = 0.893 kg. The bar is fastened by a pivot at one end to a wall which is at an angle è = 33.0 ° with respect to the horizontal. The bar is held horizontal by a vertical cord that is fastened to the bar at a distance a distance xcord = 0.635 m from the wall. A mass m2 = 0.681 kg is suspended from the free end of the bar. Find the the vertical component of the force exerted on the bar by the wall. (Take the upward direction to be positive.)

I can't quite get the picture of a wall being 33 degrees from the horizontal. Perhaps you omitted some important words.
