Steel moment of inertia
Did you know?
The moment of inertia plays the role in rotational kinetics that mass (inertia) plays in linear kinetics—both characterize the resistance of a body to changes in its motion. The moment of inertia depends on how mass is distributed around an axis of rotation, and will vary depending on the chosen axis. 查看更多內容 The 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 … 查看更多內容 The moment of inertia is defined as the product of mass of section and the square of the distance between the reference axis and the 查看更多內容 The moment of inertia of a complex system such as a vehicle or airplane around its vertical axis can be measured by suspending … 查看更多內容 The scalar moments of inertia appear as elements in a matrix when a system of particles is assembled into a rigid body that moves in three-dimensional space. This inertia matrix appears in the calculation of the angular momentum, kinetic energy … 查看更多內容 When a body is free to rotate around an axis, torque must be applied to change its angular momentum.
