Expert Answer
Moment of force:
Moment of the force is the measure of the capacity or ability of the force to produce twisting effect about an axis. This axis is perpendicular to the plane containing the line of action of force. The magnitude of moment of force is equal to the product of the force and the perpendicular distance from the axis to the line of action of the force.
Thrust:- Thrust is the force acting on a body in order to push the body in a specified direction. The exhaust gases coming out of bottom of rocket give reaction force to propel the rocket into space. Here the thrust is acting on the rocket to move upward direction against gravity. When a floating object is immersed in a liquid, the boyancy force due to the density difference of solid and liquid gives an upward thrust to the object, hence it floats in liquid against gravity.
