Question

Draw a neat labelled diagram to show the direction of two forces acting on a body to produce rotation in it. Also, mark the point about which rotation takes place. by the letter O.

Answer 1

Hint: The force that can cause an object to rotate around an axis is measured in torque. In linear kinematics, force is what causes an object to accelerate. Torque is also responsible for angular acceleration. As a result, torque can be defined as the linear force's rotational counterpart. The axis of rotation is the point at which the object rotates. Torque is the ability of a force to transform or twist in physics. Torque is defined using a variety of terminologies, including moment and moment of force.

Complete step by step solution:
In the above figure, we can see that Both the forces are in an anti-Clockwise direction and making the rod to turn in an anti-clockwise direction. The Point “O” is the midpoint of the rod and is also the center of mass of the rod. Rotation is taking place from this point O in an anti-clockwise direction.

Note: A point at which the entire mass of a body or all the masses of a system of particles appeared to be concentrated is known as the center of mass of a body or system of particles. This particular point's motion is similar to that of a single particle whose mass is equal to the number of all individual particles in the system and the resultant of all forces exerted on all particles in the system by surrounding bodies (or) the action of a field of force is exerted directly on that particle. The center of mass of the system of particles is this location.
