$4-22.$

Determine the shear and moment in the beam as a function

of $x,$ and then draw the shear and moment diagrams for the

beam.

Ans:

For $0x<mn>1</mn><mn>5</mn><mi>f</mi><mi>t</mi>$

$q,V=\{-\frac{1}{10}{x}^2+15\mathrm{.}0\}k$

$M=\{-\frac{1}{30}{x}^3+15\mathrm{.}0x\}k*ft$

For $V=-7\mathrm{.}50k$

$M=\{225-7\mathrm{.}50x\}k*ft15ft,$

$V=-7\mathrm{.}50k$

$M=\{225-7\mathrm{.}50x\}k*ft$
