The gear train transmits power from ind ond the allowable shear stress for each shaft is $6\mathrm{.}5$ ksi $.$ Assume $N_A=16$ teeth, $N_B=65$ teeth,

the diameter of solid shaft $(2)$ is $2\mathrm{.}38$ in$.,$ and the allowable shear stress for each she

$N_C=24$ teeth, $N_D=52$ teeth. Determine:

$($a$)$ the maximum power $P$ that can be transmitted by the gear train.

$($b$)$ the torque $T_E$ provided at gear $E.$

$($c$)$ the rotation speed ${}_E$ of gear $E.$

Answers:

$($a$)P=$

hp$.$

$($b$)T_E=$

lb$-$ft$.$

$($c$){}_E=$

rpm$.$
