$(3)$ Two polymer bars are connected to a rigid plate at B as shown in the Figure below. Bar $(1)$ has a cross$-$sectional area of $1\mathrm{.}65$ in$.2$ and an elastic modulus of $2,400$ksi. Bar $(2)$ has a cross$-$sectional area of $0\mathrm{.}975$ in$.2$ and an elastic modulus of $4,000$ksi. Determine the total deformation of the bar.
