The solid shaft is fixed to rigid supports at A and D$.$ The shaft consists of two different material. Dcternine the maximum shear stress at $C$ given:

$T=35$kip$-ft$

$L_1=1\mathrm{.}5ft$

$L_2=1\mathrm{.}5ft$

$L_3=3ft$

diameter $=4\mathrm{.}5$ in

$G_{AB}=5,000$ksi

$G_{BD}=6,000$ksi

Maximum shear stress at $C=$ ksi

Round answer to the ncarest tenth
