Unformatted text preview: ID # Quiz 3 (1) A uniform slender rod of length L and mass m is released from rest in the position shown, making an angle 6 with a horizontal frictionless surface. Find a formula for the angular acceleration OA of the rod, by performing the following steps. ( ) 7 points) Draw a complete free-body diagram equation for the rod. a ( (b) (6 points) Using your diagram equation, write three equations of mption for the rod. (The centroidal mass moment of inertia of a uniform slender rod is I : mL2 / 12.) (c) (3 points) Solve for a. You will need to supplement the equations of motion with the kinematic relationship between a and 61,, (the y component of the acceleration of the mass center), which is L @2045 cos6 (with appropriate plus/ minus sign).
