Question:

For the bevel gearset in Probs. 3–74 and 3–76, pp. 138 and 139 respectively, shaft AB is rotating at 600 rev/min and transmits 10 hp. The gears have a 20◦ pressure angle.
(a) Determine the bevel angle γ for the gear on shaft AB.
(b) Determine the pitch-line velocity.
(c) Determine the tangential, radial, and axial forces transmitted through the gears. Were the forces given in Prob. 3–74 correct?
