A torque $T=60N-$m Is applied to the shaft EFG, which is running at constant speed and contains gear $F.$ Gear $F$ transmits torque to shaft ABCD through gear $C,$ which drives the chain sprocket at $B,$ transmitting a force $P$ as shown. Sprocket $B,$ gear $C,$ and gear $F$ have pltch dlameters of $a=140mm,b=233\mathrm{.}338mm,$ and $c=116\mathrm{.}666mm,$ respectively. The contact force between the gears is transmitted through the pressure angle $=20.$

Combine these stresses and determine the maximum principal normal and shear stresses In the shaft

The maximum principal normal stress is MPa.

The maximum shear stress is MPa. Please answer with correct answer thank you
