Problem 2: For the beam shown below, find the reactions at the supports and plot the shear-force and bending-moment diagrams using method of section. Label the diagrams properly and provide values at all key points. Problem 3: y 500 lbf 40 lbf/in A B C x 8 in 6 in 6 in Repeat the previous problem using singularity functions exclusively (including reactions). File
