Engineering Physics I (Theory) - Web Course

s

Note on the model curriculum prepared by AICTE

Five of the seven topics listed under the heading Kinematics of Machine belongs to dynamics. These are:

i. Breaks and dynamometers
ii. Inertia force analysis
iii. Governors
iv. Gyroscope
v. Balancing

On the other hand, the model curriculum of Dynamics of Machines includes the following topic:

a. Kinematics of Gears and Gear trains

It is decided that the topics on dynamics listed above (i to v) will be covered in the course on Dynamics of Machines whereas the topic (a) above will be covered in Kinematics of Machines course.
