Page 2 The slotted arm OB is fixed to the horizontal direction (0) and the circular cam rotates in a horizontal plane about point O with an angular velocity of (t) = 16 + 12sin (0.6t) rad/s in clockwise direction, where t is in sec Assuming 80 at t=0, for the motion of roller follower A with negligible size; a) Derive an expression for the first and second order kinematic coefficients in terms of 8 and x(9) b) Determine the velocity and acceleration at r = 0.1 s. c) Plot a displacement diagram for a 360 of cam rotation (consider the prime circle of the cam), d) Explain how to determine the angle at which the min and max velocity occur with necessary mathematical expressions.
