This video develops the idea of Cams as a means of achieving a given displacement v/s time function. Evolution of different types is presented in animated form starting from the basic plate cam to achieve acceleration greater than gravity, compactness etc.
0:48 What do we achieve with Cams?
1:09 Basic Idea
1:30 Physical embodiment of Displacement — Time graph
2:15 Wedge Cam
2:25 Problem in high speed machines
3:00 Solution: Plate Cam
3:20 Disc Cam: for compactness and continuous operation
3:55 Cylindrical Cam: High speed + Compactness
4:15 Velocity and Acceleration
