You are given a task to design a cam. The cam are used for feed mechanism in automatic lathe machine. The motion of the cam follower that you need to design are given as follows: (b) 1. Move up 50 mm in 1 second using the harmonic motion 2. Dwell for 0.5 s 3. Move down 50 mm in 1 second using the harmonic motion 4. Dwell for 1 second The motions of the cam follower then will repeat the same sequences. (i) Calculate total time taken for the cam to complete a full circle motion. (ii) Calculate the rotational speed of the cam. (iii) Determine the cam rotation angle for each of the follower motion interval. (iv) Construct the follower displacement diagram for this cam

The crank torque diagram can be simplified to a triangle having the following values: Angle 0° Torque (Nm) 0 (a) What is the mean torque? 60° 4500 180° 180° to 360° 0 0 (b) What moment of inertia of flywheel is required to keep the speed to within 180 ± 3 rpm? (c) If one cylinder of the engine is made inoperative and it is assumed that the torque for this cylinder is zero for all crank angles, determine the fluctuation in speed at 180rpm for the same flywheel. (a) 3375 Nm (b) 50kgm (c) ±21 rpm

A four-bar mechanism is used to transmit power to slider E. Link AC rotates counterclockwise at 100 rpm. A and B are fixed points. The following linkages are measured in cm: AC=35, AB=70, CD=45, BD=45, DE=40. Find the instantaneous velocity of slider E in cm/s 1.Draw the mechanism in appropriate scale on your paper2. Find the instantaneous linear velocity of C3. Find a point on your paper to draw the velocity polygon and scale the magnitude of the computed linearvelocity4. Use the relative velocity equation for finding the linearvelocity of D; ? = ? + ?? ? ?/?5. Remember that although the magnitudes are unknown, their directions can be identified6. Obtain the magnitudes of the unknown velocities from the velocity polygon7. For Link DE, repeat the process by using ? = ? + ??the line as much as needed8. Remember that E is a SLIDER therefore it can only goin the direction where its movement is not constrained? . Add the vector ? to the head of ? and extend?/? ?/??
