Answer to Question #210157 in Civil and Environmental Engineering for Ri Jin

Question

The figure is in this link https://ibb.co/4fZmNBs

For the beam shown with E = 29 x 106 psi, determine the slope and deflection at the end C using deflection by integration.

Answer 1

QA= ML/6EI

ML= $\intop$^L₀ mM/EI dx = $\int$ ³⁰₀ [(4x)(x/10)dx]/EI + $\intop$¹⁰₀ [(8X)( 2X/10)dx]/EI

= (200K.ft³(14)³in³/ft³)/(29*10³k/in³)(24in⁴) = 0.980618

= 0.981 in (up)
