gear transmits 5000 l6 - chaft having a diameter of 2.25 in. A square key 0.50 in. on a side connects the shaft to the hub of the in. of lorque to a circular gear, as shown in Figure P4-30. The key is made rom SAE 1020 cold-drawn steel. Determine the equired length of the key, L, to be safe for shear and bearing. Use a design factor of 2.0 based on ield for shear and the AISC allowable bearing tress.

Question
A gear transmnits 5000 lb in. of torque to a circular
shaft having a diameter of 2.25 in. A square key
0.50 in. on a side connects the shaft to the hub of the
gear, as shown in Figure P4-30. The kcy is made
from SAE 1020 cold-drawn steel. Determine the
required length of the key, L, to be sale for shear
and bearing. Use a design factor of 2.0 based on
yield for shear and the AIISC allowable bearing
stress.
