Unformatted text preview: FALL 2007 Name:_____________________________ ENME361: MID-TERM EXAM I PLEASE PAY ATTENTION TO THE FOLLOWING: 1. Be neat 2. Five Problems, not equally weighted 3. State all assumptions made and provide steps 4. Maximum time allowed for exam: 75 minutes 1. (15) A pendulum of mass m attached to a moving pivot of mass M is shown. Assume that the pivot cannot translate in the vertical direction. Let the horizontal translation of the pivot point from the fixed point O be measured by the coordinate x and the angle be used to describe the angular displacement of the pendulum from the vertical: 1. Determine the absolute velocity of the pendulum, and 2. Assuming that the bar to which the pendulum mass m is connected is massless, determine the kinetic energy for the system. l m O M Pivot, ' O x l m O M Pivot, ' O x 2. (15) Consider the pulley system shown. The mass of each pulley is small compared with the mass m and, therefore, can be ignored. Furthermore, the chord holding the mass is inextensible and has negligible mass. Obtain the equivalence holding the mass is inextensible and has negligible mass....
