Unformatted text preview: 3 [2] The uniform disk of mass m and radius R is attached to a spring of stiffness k . If the disk is released from rest with the spring undeformed, determine the expression for the maximum angular velocity of the disk. Assume that the disk rolls without slipping on the inclined surface. (In a disk rolls without slipping the center has velocity and acceleration of magnitudes R ω and R α , respectively) (35 points ) k R 30° 4 [3] The homogeneous bar AB of mass m and length L is released from rest in the position θ = o . (a) Determine the angular acceleration and angular velocity of the bar as functions of , m , and L . (b) Find the maximum value of the vertical component of the pin reaction at A and the value of at which it occurs. (35 points ) L m A θ...
