Therefore dividing through, top and bottom, by A, y =

But P/A = a and (n2El)/(L2A) = oe (the Euler stress for pin-ended struts)

Therefore total deflection at any point is given by y + yo =

Maximum deflection (when x — 0) = maximum B.M. = P

Co oe

C0h where h is the distance of the outside fibre from the N.A. of the strut.

Therefore the maximum stress owing to combined bending and thrust is given by

0 0
