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

Your bicycle has 10 gears, from low (easiest to pedal) to high (hardest to pedal). When you first start peddling, you usually use a low gear to accelerate from standing and then shift to a higher gear when you are at a high cruising (ground) speed so that you are always pedalling against the same resistance. One morning you forget to shift down and you try to start in a very high gear. Despite the fact that you usually go fast in high gear, you can't get anywhere at all. The next day you remember to start in low gear, but you forget to shift up. So you ride to school at the same ground speed as usual but in low gear all the way. Despite the fact that there is less resistance to pedalling in the low gear, your legs get more tired than usual. Using you knowledge of force and resistance explain why they are more tired? Explain which skeletal fibers will be utilized in this case?
