P.5) A system consisting of two elastically constrained masses m₁ and m₂ is free to slide on a friction- less rod that rotates about the pivot point O. Mass m₁ is attached to O along the rod by a spring of stiffness k₁ with a free length of 1₁, and m₁ and m₂ are connected by a spring who sestiffness and free length are k₂ and 12, respectively. The angle describes the rod's orientation relative to the horizontal, and the positions of m₁ and m₂ along the rod are given by L₁ and L2, respectively. Find expressions for the system's total kinetic and potential energies. min m Ꮎ ← j L₁ X

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.
