Q1(3). The beam is supported by a pin support at point A and a rocker support at point B, and the length is /= 2.8 ft. It has a cross section shown in the image with h = 7.4 in. It is subjected to a uniformly distributed load with load intensity w = 916 lb/ft, and a couple moment of 1500 lb-ft as shown. Point C is located immediately to the right of the couple moment, and the vertical location of point C is also shown in the cross section. If the location of point C is indicated on the cross section, and its state of stress can be represented on plane element as shown, determine the smallest (in magnitude) angle of rotation 0 (in the unit of °) to achieve the principal stresses in x-y plane for this element at point C. Negative sign must be included if the rotation is clockwise. W 1500 lb ft 6 ft Txy + B ox 30° 1in. 2 in. C 6 in. H 1in. 1in.
