Moment of Inertia of Rod having non-uniform, linearly increasing mass density

Moment of Inertia of a Rod having non-uniform, linearly increasing mass density

Leave a Comment / Mechanics /

Moment of Inertia of Rod having non-uniform, linearly increasing mass density Moment of Inertia Moment of inertia is of great importance when we come to discuss the rotational dynamics. The the word “inertia” refers to resistance against any change in state of object (mass). Specifically, the moment of inertia is measure of a body’s resistance […]

Rolling of a solid disc on horizontal and its K.E. energies Mechanics 10 Important Problems for IIT-JEE and NEET

A solid disc is rolling without slipping on a horizontal ground as shown in figure. Its total kinetic energy is 150 J . What are its translational and rotational kinetic energies respectively?

2 Comments / Mechanics /

Rolling of a solid disc on horizontal Rolling , specifically a pure rolling is a classic example of combined translational and rotational motion. While talking about the rolling of a  solid disc over horizontal ground, actually we are discussing a simple case of rolling. Pure rolling refers rolling without slipping. Thus, there is no presence

7 Comments / Blog /

Count of Beats : How to determine the frequency of Unknown Tuning Fork Beats is a popular word among musician. Using beats formation concept, they tune their instruments while playing them against some standard frequency. All instruments come into tune when beats disappear. Now the instruments sound with same standard frequency which implies that there has
