Question

Relative acceleration: Need help with this problem. Please see the attached JPG

Answer 1

It would appear since the acceleration is upward and the collar can only move at a path which is 45 degrees from the vertical, the acceleration force in that direction would be .707(4 meter/sec^2) Just a swag lol.

Answer 2

Thanks for replying but book answer says that a=7.49 m/s^2 at an angle of 22.8 degrees measured from neg-x axis counterclockwise.

Answer 3

It was just a guess (with some wrong thinkin)

Answer 4

The collar C would have two accelerations - one in the upper direction, and one along the shaft AB. Can you find the resultant of these two vectors?
\[a=\sqrt{a 1^{2}+a2^{2}+2a1a2\cos 45}\]
a1=4
a2=4cos45
