Question
For the truss shown in the figure below, assume that the loads are being transmitted to the bottom
chord and draw the influence lines for member DI and EK. Also, considering the 3-point moving load
as shown, determine the following member forces. Assume that the loads move only to the right.
a. Maximum tension on member DI in kN, put “0” if none.
b. Maximum compression on member DI in kN, put “0” if none.
c. Maximum tension on membe EK in kN, put “0” if none.
d. Maximum compression on member EK in kN, put “0” if none.
Note that
a = 5.1 m
b = 6.3 m
c = 62 kN
d = 78 kN
