Homework 7/27



I have been able to find all the values in this problem except for the a_B. The equation I am using is a_B = a_A + (a_B/A) + (alpha x r_B/A) + 2(omega) x (v_A/B) + omega x (omega x r_B/A). I have found that the only components not equal to zero would be a_A and omega x (omega x r_B/A) yet when I calculate I get an incorrect answer. Any ideas?

You should also have a non-zero contribution from alpha x r_B/A (not sure if that was a typo, but your post suggests that this term did not appear in your solution).

Is the theta in the picture pointing in the direction of positive theta? If so then would a positive theta dot be in the -i direction?

Yes, the angle theta defined in the problem would be in the negative x direction (by the right hand rule).
