Question

Section 5. Problem 13 (25 pts.) For the below beam the loads are: 10 (k), 3 (k-ft.). 9 (k) and 5 (k). The reactions for the beam are: R(B) 3.142857142857143 (k), R(E) - 56.857142857142854 (K) a) Draw the shear and moment diagram for the beam. Show all work on the material turned into the ELC. Label all points. b) Using singularity functions write the equations for shear and moment for the beam. Show all work on the material turned into the ELC To submit work for this problem type in the value of the point load at the left end (k). AK Ck Bkft.
