What role do constraints play in the analysis of mechanical systems? (2021)
Step 1: Understand what a mechanical system is. A mechanical system is made up of parts that move and interact with each other.
Step 2: Learn about degrees of freedom. Degrees of freedom refer to the number of independent ways a system can move. For example, a ball can move in three directions: up/down, left/right, and forward/backward.
Step 3: Know what constraints are. Constraints are rules or limitations that restrict how a system can move. For example, a hinge allows rotation but prevents sliding.
Step 4: See how constraints affect motion. When constraints are applied, they reduce the number of ways the system can move, which simplifies the analysis.
Step 5: Understand the impact on equations of motion. With fewer degrees of freedom, the equations that describe the motion of the system become simpler and easier to solve.
