Segments AB and BCD of beam ABCD are pin connected at x = 10 ft. The beam is supported by a pin support at A and roller supports at C and D; the roller at D is rotated by 30° from the x axis. A trapezoidal distributed load on BC varies in intensity from 5 lb/ft at point B to 2.5 lb/ft at point C. A concentrated moment is applied at joint A, and a 40-lb inclined load is applied sat the midspan of CD. (a) Find reactions at supports A, C, D. (b) Find the resultant force in the pin connection at B
