Problem #$2-20$ pts$.$

The cantilever beam given below is embedded into the wall at A$.$ Draw the free$-$body diagram and find the reactions at the support end $A.(5$ pts$.)$

The width of the beam is $1\mathrm{.}75$ in $.$ If ${}_b=20$ksi and ${}_d=10$ksi, find the required height of the rectangular beam to carry the bending and shear $($transverse$)$ loads. $(15$ pts$.)($hint: draw your shear and moment diagram to find max shearing force and max bending moment$).$
