5-1. Determine the force in each member of the truss, and state if the members are in tension or compression.
I have the correct answer provided, just lookng for a more detailed breadown of how the answer was obtained thanks.
Q1. Statically indeterminate beam analysis.
a) Calculate the BMs (bending moments) at all the joints of the beam shown in Fig.1
using the moment distribution method. The beam is subjected to an UDL of w kN/m.
L1= 0.4L. Assume the support at C is pinned, and A and B are roller supports. E = 200
GPa, I=250x106 mm². Use the values of w = 50 kN/m and L = 6
b) Draw the shear force and bending diagrams for the entire beam.
c) Calculate the BMs at all the joints of the same beam shown in Fig.1 using the slope
deflection method.
d) Compare the values of BMs obtained using the two methods a) and c) and comment.
