Vehicle Dynamics

Vehicle Dynamics workshop will impart most intense experiences with great learning opportunity that too in a classroom environment. It is all designed to understand how, why and how much certain factors can affect the performance of a vehicle. All live demonstrations will make participants to interact and ask questions to get collaborative feedback.Participants will be covered with every aspect of vehicle dynamics and wrap up with data acquisition and analysis.

Prerequisites:-

Can access computer system and make use of internet to perform search over Google.

 

Need to Prepare?
