The figure shows a variable speed friction device. Axis A has an
angular velocity of 16 Rad / sec in the direction shown and Axis C
has an angular velocity of 30 Rad / sec in the same direction.
determine the proper mounting and draw a dimensional drawing of the
device
Homework Answers
Given
Since disc A and C rotate in the same direction the disk B should be between the axes of disc A and C(contact velocity are in opposite direction at A and C)
For the disc B to rotate in the same axes(Not rotate with disc A or C)
The contact velocity should be equal and opposite ar A and C

The figure shows a device that can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.756 m, and rotating with an angular speed of 86.1 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is = 0.177 rad. From these data, determine the speed of the bullet....
