平衡と弾性

A rigid body is said to be in dynamic equilibrium when both its linear and angular acceleration are zero, relative to an inertial frame of reference. This …

Static equilibrium is a special case in mechanics that is very important in everyday life. It occurs when the net force and the net torque on an object or …

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the …

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. …

A rigid body is said to be in static equilibrium when the net force and the net torque acting on the system is equal to zero. To solve for rigid body …

A rigid body is in static equilibrium when the net force and the net torque acting on the system are equal to zero. Consider two children sitting on a …

When a force is applied on a body, it undergoes deformation. In order to restore the body to its original shape and/or size, an opposite or restoring …

The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or …

Elasticity is the ability of an object to withstand the effects of distortion and to return to its original size and shape once the forces causing …

Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. …

Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static …

Stress is a quantity that describes the magnitude of a force that causes deformation, generally defined as internal force per unit area. When forces pull …
