How to find the Degree of freedom (Mechanics) of system?
Thank you so much.
Thank you so much.

The degree of freedom in mechanics refers to the number of independent parameters or variables that are required to describe the motion of a system. It represents the number of ways in which a system can move or change its configuration without violating any constraints or equations of motion.
The concept of degree of freedom is important because it helps us understand the complexity of a system and how many variables are needed to fully describe its motion. It also allows us to determine the number of equations of motion that are required to solve a given problem.
The degree of freedom is directly related to the number of dimensions in a system. In general, a mechanical system in 3-dimensional space has 3 degrees of freedom, which correspond to the 3 possible axes of motion. However, in certain cases, the number of degrees of freedom can be less than 3, such as in a constrained system.
A constrained system is one in which the number of degrees of freedom is less than the number of dimensions, as some variables are restricted due to constraints or boundary conditions. On the other hand, an unconstrained system has the same number of degrees of freedom as the number of dimensions, meaning all variables are free to vary.
The concept of degree of freedom is applied in various fields, such as engineering, physics, and robotics, to analyze and design systems. It is used to determine the number of actuators or control inputs needed to achieve a desired motion, and to identify any potential constraints or limitations in a system. It is also used in computer simulations and modeling to accurately represent the behavior of complex systems.
