Problem 450 - Reactions at Hinge Support of the Frame Holding

Problem 450
The billboard BC weighing 1000 lb is subjected to a wind pressure of 300 lb/ft as shown in Figure P-450. Neglecting the weights of the support-members, determine the component of the hinge forces at A and F.

Problem 239
The 16-ft wing of an airplane is subjected to a lift which varies from zero at the tip to 360 lb per ft at the fuselage according to w = 90x1/2 lb per ft where x is measured from the tip. Compute the resultant and its location from the wing tip.
