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. Then state function and significance of that angle for the design of cam mechanisms. Corine low x+x-2 ex cor (79) (9212=112+x 2+2102).xcar -A B 01=5obab T m O 0.1 0.1 m m + degen sobti
