Can anyone figure this outQ$7\mathrm{.}3\mathrm{.}1$ A $4m$ long steel cantilever beam is subjected to combined distributed load $q$ of $3k\frac{N}{m}$

and concentrated load $P$ of $4kN,$ as shown in Fig. $7\mathrm{.}3\mathrm{.}1.$ If the beam has a width of $50mm$ and a

depth of $100mm$ with a Young's modulus of $204$GPa, determine the angle of rotation at the free

end and maximum deflection using the superposition method. $($Hint: use the known individual

slope and deflection results of single loading cases.$)$

Answers: $,0\mathrm{.}047$ radian and $0\mathrm{.}144m.$
