MIME 2300 Test 2 Name _______________________ April 6, 2007 In all the problems show all equations used with variables and then with values substituted so partial credit can be given wherever possible. Give units on all answers and write only in the space provided. On problems where appropriate, draw coordinate systems, datums, FBDs, K.Ds or velocity diagrams. Do not use F=ma as the primary method to solve any problems on this test ! 1. In the mechanism shown points D and E are fixed pins. Member DC rotates about point D with the motion shown. Member CB is pinned to DC at C and is free to rotate about C. Member CB is horizontal and passes through the slider, 2 and slider 2 is pinned to the ground at E but is free to rotate about point E. The angular velocities of the two links are as shown when the mechanism is in the current position. If the distance between C and E is decreasing at the rate of 37.6 in/s at the time shown, find the angular acceleration of member CB.
