The linkage shown below is made up of two 3-kg rectangular members (0.4 m by 0.1 m), and is flying through the air. At the instant shown, the vertical member has angular velocity 4 rad/s, and the angled member has angular velocity 1 rad/s.
a. What force vector does the angled member apply to the vertical member (use the inertial CS drawn in the top right corner of the figure)?
b. In the non-inertial CS fixed at the top of the vertical member, the motion of the point A is different than the motion calculated in an inertial CS. Give a differential equation for the position of A in this NICS.
