We will use moment equilibrium around the $x-$axis to calculate the $x-$component of the reaction torque at

$A,T_x^A,$ and the axial torque resultant at section $C,T^C=T(x^C),$ for these two shafts in torsion.

HW$5\_1\_1$

For the top shaft, obtain the numerical value, in $N*m,$ for:

$T^C=,N*m$

$T_x^A=$

$N*m$

HW$5\_1\_2$

For the bottom shaft, obtain the numerical value, in $N*m,$ for:

$T^C=$

$N*m$

$T_x^A=$

$N*m$
