SOLVE PART D PLEASE!!!

$2.)(27$ Points$)$ The shaft shown in the following figure is $200$ mm long between self $$ aligning bearings at A and B$.$ Belt forces are applied to the center pulley as shown. The left end of the shaft is connected to a clutch by means of a flexible coupling. Nothing is attached to the right end of the beam $($i$.$e$.$ The right end of the shaft is free to rotate.$).2500$ N $750$ N a$.)$ Determine and show the stress components on volumetric elements located at the side $($point S where the maximum normal stress due to bending will occur$)$ and at the top $($point T where the maximum combined torsional and transverse shear stress will occur $).$ Note that points T and S are adjacent to the pulley. b$.)$ Find the principle stresses $(1,2,3)$ and the absolute maximum shear stress $$ for each of the two locations S and T$.$ c$.)$ Comparing points S and T$,$ what is the maximum shear stress in the shaft material and what is the maximum normal stress in the shaft material? d$.)$ If the shaft is made from $1020$ Hot Rolled steel which has a tensile yield strength of $=290$ and a shear yield strength of about $58\%$ of the tensile yield strength $($i$.$e$.=\mathrm{.}58()),$ what is the Factor of Safety corresponding to normal stress and what is the factor of safety corresponding to shear stress? $($Assume failure of the steel is defined by yielding.$)$ Partial Ans. $($Point T$)1=73\mathrm{.}74,2=73\mathrm{.}74,3=0,($Point S$)1=226\mathrm{.}7,2=19\mathrm{.}7,3=0,=123\mathrm{.}2=226\mathrm{.}7$
