$6\mathrm{.}2-7$ A beam with a guided support and $4m$ span supports a distributed load of intensity $q=4k\frac{N}{m}$ over its first half $($see figure part a$)$ and a moment $M_0=5kN*m$ at joint $B.$ The beam consists of a wood member $($actual dimensions $97mm295mm$ in cross section, as shown in the figure part b$)$ that is reinforced by $7-mm$ thick steel plates on top and bottom. The moduli of elasticity for the steel and wood are $E_s=210$GPa and $E_w=10$GPa, respectively.$($;Sir please tell me in free body diagram why the guided support reactioreactions are not taken and also the roller support reactions are not taken$)($a$)$Calculate the maximum bending stresses in the steel plates and in the wood member due to the applied loads. $($b$)$ If allowable bending stress in the steel plates is $100$MPa and that in the wood is $6\mathrm{.}5$ MPa find qmaxmum. $($Assume that the moment at B $,$ Mo$,$ remains at $5$kNm$.)($c$)$ If q $=4$ kN$/$m and allowable stress values in part $($b$)$ apply, what is Mo$,$max at B$?$
