Determine the shear v(x) and moment m(x) throughout the beam as a function of x. draw the shear and moment diagrams for each member of the frame. assume a is fixed, the joint at b is a pin, and support c is a roller.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
