The wheels of the overhead crane exert downward forces on the horizontal I-beam at B & C. The force at B is 40 kip and the force at C is 44 kip. (a) Determine the magnitude and direction (CW or CCW) of the resultant moment about point A due to the forces acting at B & C. (b) Determine the magnitude and direction (CW or CCW) of the resultant moment about point D due to the forces acting at B & C. -10 ft - 15 ft -25 ft D

For the simply supported beam shown, draw influence lines for moment at C (12-ft from support A), and reaction at B. Clearly identify critical points on the influence lines with ordinates. The beam supports a uniform dead load of 100 lb/ft, a live load of 400 lb/ft, and a single live concentrated load of 10-kips. What is the maximum positive and negative moments at C? A is a pin and B is a roller. A オ 12 12-7 12 24 C.

Determine the internal normal force, shear force, and bending moment in the beam at point D. Assume the support at A is a roller and B is a pin.
