The plastic sheet, 1/2 in. thick, is bonded to the pin-jointed steel frame. Determine the magnitude of the force P that would result in a 0.18-in. horizontal displacement of bar AB. Use G = 70 x 103 psi for the plastic, and neglect the de- formation of the steel frame. 3 ft B Plastic sheet ! ft The plastic sheet, 1/2 in. thick, is bonded to the pin-jointed steel frame.
