Moment of inertia of a bar about its end

Web12 sep. 2024 · A simple pendulum is defined to have a point mass, also known as the pendulum bob, which is suspended from a string of length L with negligible mass (Figure 15.5.1 ). Here, the only forces acting on the bob are the force of gravity (i.e., the weight of the bob) and tension from the string. The mass of the string is assumed to be negligible … Webmoment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force). The axis may be internal or external and may or may not be fixed. The moment of inertia (I), however, is always specified with respect to …

Web24 apr. 2024 · If the moment of inertia of a rigid body about an axis through its center of mass is given by I c m, then the moment of inertia around an axis parallel to the original axis and separated from it by a distance d is given by (5.4.5) I = I c m + m d 2 where m is the object’s mass. Proof The moments of inertia of a mass have units of dimension ML 2 ([mass] × [length] 2). It should not be confused with the second moment of area, which is used in beam calculations.
