Question

Hello,

Need help with part b)

 

Thank you,

5. a)
For the beams shown below, draw the influence lines from points through for:
i) bending moment at point
ii) shear force immediately left of point, and
iii) bending moment at point
For each influence line, calculate and indicate the value of the influence
coefficient that has the maximum absolute value.
