Show me the steps to solveExample $1$:

Consider the following beam and

determine the

expression for $$ at the centre of a beam

of rectangular cross section shown,

in terms of $V,b$ and $d.$

ANS $=\frac{3V}{2A}$

Example $2.$

Consider the following beam and determine the

expression for $$ at the positions about the beam

shown and at the centre. The beam is of uniform

thickness.

Assume $V=100kN$ and the beam is loaded about

Its major axis Ixx.

ANS:

Values in mm$.$

At position $1$ and $4,$

$A=0$ therefore $=0$

At positions $2$ and $3,=2\mathrm{.}435\frac{N}{m}{m}^2$
