It is possible that -while writing torque equation about instant centre of rotation, we may get a pseudo torque term
Shreyas Samudra said:what if a bar is moving on frictionless floor (translating + rotating) and such that its angular speed is increasing ,
so instant centre is to have some angular acceleration
The instantaneous centre of rotation is a point in a rigid body that has zero velocity at a specific instant in time. It is the point around which all other points in the body appear to be rotating at that instant.
The instantaneous centre of rotation is determined using the concept of relative motion. It is the point where the velocities of two points in the body are perpendicular to the line connecting them, and the magnitudes of the velocities are inversely proportional to the distances from the point.
The instantaneous centre of rotation is important in understanding the motion of rigid bodies. It helps in analyzing the motion of complex systems and predicting future positions of the body.
No, the instantaneous centre of rotation can change depending on the motion of the body. It can also vary for different points on the body.
Yes, the instantaneous centre of rotation can be outside the body if the body is undergoing non-uniform motion. This means that different points on the body have different velocities, leading to a point outside the body being the instantaneous centre of rotation.
