Problem $4($part$1)$

A beam with an overhang is supported and loaded as shown in the figure below. The beam cross$-$section

has widths $w_1=1$ in and $w_2=0\mathrm{.}4$ in$,$ and a height $h=3\mathrm{.}2in.$

a$.$ Calculate the support reactions at A and $B$

Answer:

a$.B_y(\frac{?}{b})=$

$C_y(Ib)=$

Problem $4($part $2)$

b$.$ Determine the maximum bending moment in the beam.

c$.$ Determine the maximum tensile and compressive stresses in the beam.

d$.$ If the allowable stresses in tension and compression are $20$ksi and $15$ksi, respectively, what is the

required height $h$ of the beam? Assume that both widths remain the same.

Answer:

b$.M_{\text{m}\text{a}\text{x}}(Ib*ft)=$

c$.{}_{T,\text{m}\text{a}\text{x}}(ksi)=$

${}_{C,\text{m}\text{a}\text{x}}(ksi)=$

d$.h(in)=$
