Question

What is a multi body systems in biomechanics? A system of different forces, which act together. A system of geometric bodies, which are coupled. A system of masses, which are moving to each other. A system of forces and moments, which are acting together.

Answer 1

A multi-body system in biomechanics refers to a system of geometric bodies that are coupled together, such as muscles, bones, and joints. These bodies work together to produce movement, and the forces and moments acting on them determine their motion and interactions within the system.

Step-by-step explanation:

In biomechanics, a multi-body system refers to a system of geometric bodies that are coupled together. These bodies represent different parts of the human body, such as muscles, bones, and joints, which work together to produce movement. The forces and moments acting on these bodies determine their motion and interactions within the system.

For example, when analyzing the movement of a ball bouncing on the ground, the ball itself would be considered as the system of interest. In the case of a car crash, both cars together would form the multi-body system.

It's important to note that external forces acting on the system must cancel each other out in order for the system's momentum to remain constant.
