Unformatted text preview: Problem: The disk rotates with a constant clockwise angular velocity of 12 rad/s. At the instant shown determine the following: 1. The angular velocity and angular acceleration of rod BD BD BD 2. The velocity and acceleration of the point on the rod coinciding with E vE aE TO EARN CREDIT, YOU MUST SHOW ALL OF YOUR WORK (LEGIBLE AND CLEARLY ORGANIZED). USE EXTRA PAPER AS NECESSARY Problem: A circular gear is welded to the rigid body shown, the combined mass and moment of inertia of which are m and I = 3m, respectively. The circular gear rests on a rack inclinded at 60o to the horiztonal. The rigid body/gear assembly is released from rest in the position shown. Determine the angular acceleration of the rigid body/gear assembly immediately after it is released. Hint: use the coordinate system shown to simplify your calculations. Show work for credit. Continue on back if necessary. The equation sheet is on the back side of page 2. ...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
