Question

define rigid body and center of mass and how center of mass of rigid body is determined​

Answer 1

Answer:

rigid body means solid body and centre of mass refers to thecentre of the body where mass is balanced.

Answer 2

Explanation:

a)The center of mass:

1.The center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero.

2.This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration.

b)Single rigid

1.In case of a single rigid body, the center of mass is fixed in relation to the body.

2.If the body has uniform density, it will be located at the centroid.

Determined:

1.The total mass times the acceleration of the center of mass equals the sum of external forces.

2.For the translational motion of a rigid body with mass M, Newton's 2nd law applies as if we are describing the motion of a point particle (with mass M) under the influence of the external force.
