Kinematics with MicroStation Ch 07a Cams Concept & Types

Complete Kinematics course made in MicroStation http://www.Bentley.com ; for deeper, intuitive learning without abstract formality and dry rigor for its own sake.

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.

0:11 Motivation
0:48 What do we achieve with Cams?
1:09 Basic Idea
1:30 Physical embodiment of Displacement -- Time graph
1:55 Animation
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

all the kinematics videos are amazing. very helpful. learning through 3-d figures n videos makes it more easier n increases understanding and interest in the subject! thanks a lot! keep up and continue the good work!:)

@bitchingstrategy Thank you! I enjoyed every minute of making these videos and teaching this subject. Glad that joy is shared! Looking forward to your continued support . . .

@sonakshi1513 the "upper curve" of the cam curve pulls the roller and the rod downwards if the speed of the roller is so great that the gravitational acceleration is not enough to make the rod and roller fall in sync with the cam's curve. i hope i was clear enough.

sir help me to understand how is acceleration more than gravity achieved in case of plate cam.
