Question $2[8$ marks$]$ Macaulay's Method Problem.

For the given simply supported beam with combined load as shown. Calculate the deflection at point D and the

maximum deflection. On calculation, Slope is going to be zero at $x=2\mathrm{.}812m.$ Take $E=200$GPa and $I=20{10}^{-6}{m}^4$

Sectioning Method: $4$ marks; Step wise solving: $2$ marks; Correct slope deflection equation and result accuracy:

$2$ marks
