Civil Engineering MCQAE Level Civil Engineering
A simply supported prismatic beam carries a transverse UDL w and an axial compressive load P. The transverse-load vs central-deflection curve will be linear if

Choose the correct answer
A
material is linear and P > 0
B
material is linear and P = 0
C
material is nonlinear and P > 0
D
material is nonlinear and P = 0
Correct Answer
B. material is linear and P = 0
Why is this the answer?
Linearity requires linear-elastic material AND no axial load; axial compression introduces the (nonlinear) beam-column P-δ effect.
