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 I 1 (60.28 KiB) Viewed 45 times

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 Cis 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 8p (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. A 1 C W 1500 lb ft . 6 ft- Txy t B ox 30° 1in. 2 in. C 6 in. HHI HTSAT 1in. 1in.
