Transcribed Image Text:Problem 3:
The figure shown is a geared countershaft with an overhanging pinion at C. Select an angular-
contact ball bearing from Tables below for mounting at O and a straight roller bearing for mount-
ing at B. The force on gear A is FA = 600 lbf, and the shaft is to run at a speed of 480 rev/min.
Solution of the statics problem gives force of bearings against the shaft at O as
Ro = -387j + 467k lbf, and at B as RB = 316j – 1615k lbf. Specify the bearings required, using
an application factor of 1.4, a desired life of 50 000 h, and a combined reliability goal of 0.90.
