Analysis of a Cam-Follower Arm
Problem: A beam is supported on two pins in bearings having small clearance. Estimate its maximum deflection and spring rate at the load point.
Given: The beam dimensions in Figure 8-23 are: a = 8, l = 20, b = 0.75, h = 2, d = 0.5 in, e = 0.375 in, f = 0.438 in, and g = 0.375 in. The pin holes are all 0.5-in-dia. The load F = 100 lb. The beam and pins are steel and the bearings are bronze on steel. The beam cross section is tapered and pocketed to reduce its mass. The basic geometry is as in Example 8-4.
Assumptions: Loading and support reactions are parallel but out of plane. Pin supports are significantly stiffer than the beam.
