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 mattached to a moving pivot of mass Mis shown. Assume that the pivot cannot translate in the vertical direction. Let the horizontal translation of the pivot point from the fixed point Obe measured by the coordinate xand the angle θbe 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 mis connected is massless, determine the kinetic energy for the system. mθOMPivot, 'Oxl
