WebApr 29, 2024 · In motion control applications, inertia is generally given as J (as shown in the equation above) and is defined as “mass times radius squared.” However, in many rotating equipment applications, inertia is given as either WR2 or WK2 and is defined as “weight times radius squared.” WebRotational inertia is given the symbol I I. For a single body such as the tennis ball of mass m m (shown in Figure 1), rotating at radius r r from the axis of rotation the rotational inertia is I = mr^2 I = mr2 and consequently …

WebThe moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration.It depends on … WebDec 22, 2024 · Angular momentum (the rotational analogue for linear momentum) is defined as the product of the rotational inertia (i.e., the moment of inertia, I ) of the object and its angular velocity ω ), which is measured in degrees/s or rad/s. You’ll undoubtedly be familiar with the law of conservation of linear momentum, and angular momentum is also ...
