Determine the Shear Force and Bending Moment Equation
The 13-ft long beam ABCDE is simply supported with concentrated loads of 2000 lb at points A and D and a distributed load of 1000 lb/ft between points C and D as shown. The roller support at B exerts an upward force of 6000 lb on the beam and the pin support at E exerts an upward force of 4000 lb on the beam.
a. Draw the shear force graph for this beam.
b. Draw the bending moment graph for this beam.
c. Using the coordinate axes shown (with its origin at B), write the shear force equation for segment CD of the beam (2 ft < x < 8ft).
d. Using the coordinate axes shown (with its origin at B), write the bending moment equation for segment CD of the beam (2 ft < x < 8ft).
