A translating cam-follower is to be designed for a Rise-Dwell-Fall-Dwell (RDFD) application in which vibrations must be considered. The cam is to move the follower from 0 to 35 mm in 70°, dwell for 100, fall back to 0 mm in 80°, and dwell for the remainder of the cycle. In addition, the cam must rotate at an angular velocity of 60 RPM. The position (s), velocity (v), and acceleration (a) curves during the rise period are defined by the...

2.91 Replace the force F = - 2800i + 1600j + 3000k lb acting at end A of the crank handle with a force R acting at O and a couple vector Cr. (b) Resolve R into the normal component P (normal to the cross section of the shaft) and the shear component V (in the plane of the cross section). (c) Resolve CR into the twisting component T and the bending component M.
