Unformatted text preview: 2. The 6lb slider is released from rest at point A and slide with negligible friction in a vertical plane along the circular rod. The attached spring has a stiffness of 2 lb/in. and has an unstretched length of 24 in. To determine the velocity of the slider as it passes position B , (a) Derive the dynamic force equilibrium equations in the normaltangential coordinate system (20 points) (b) Determine the velocity of the slider as a function of θ (30 points). (c) Determine the normal reaction force from the rod to the slider when the slider passes position B (20 points). (d) Determine the velocity of the slider as it passes position B using the principle of work and energy ( Extra Credit: 20 points ) 3 ME 215  Vector Dynamics Midterm Exam Summer 2006 Name: _____________________________ Bronco ID: ______________________ 4 ME 215  Vector Dynamics Midterm Exam Summer 2006 Name: _____________________________ Bronco ID: ______________________ 5...
