State and prove the perpendicular axis theorem Notes pdf ppt
Perpendicular Axis Theorem: The theorem states that “the moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of the moments…
Some Typical Bodies and their Moments of Inertia: Notes pdf ppt Engineering Mechanics
Moments of Inertia: Moment of inertia is the name given to rotational inertia, the rotational analog of mass for linear motion. It appears in the relationships for the dynamics of…
Definition of Moment of Inertia: Notes for Engineering Mechanics
Moment of Inertia: Moment of Inertia (Mass Moment of Inertia) – I – is a measure of an object’s resistance to change in rotation direction. Moment of Inertia has the…
Centroid for Curved Areas: Notes pdf ppt Engineering Mechanics
Centroid for Curved Areas: Taking the simple case first, we aim to find the centroid for the area defined by a function f(x), and the vertical lines x = a…
What is Center of Mass: Notes pdf ppt Engineering Mechanics
