Consider the two particles at the position 49 cm and 51 cm. The two bodies of mass m and radius r are moving along the common tangent. Therefore moment of inertia of the first body about XY tangent.

Moment of inertia at the centre and perpendicular to the plane of the ring. So, about a point on the rim of the ring and the axis? Thus if boy rotates with angular speed the umbrella rotates with angular speed.

But the motion of the platform is due to third law pair torque on it vis-a-vis torque on the umbrella. Find the moment of inertia of the second wheel. If I be the moment of inertia of the second wheel, we have from the conservation of angular momentum. A kid of mass M stands at the edge of a platform of radius R which can be freely rotated about its axis.

The moment of inertia of the platform is I. The system is at rest when a friend throws a ball of mass m and the kid catches it.

If the velocity of the ball is horizontally along the tangent to the edge of the platform when it was caught by the kid, find the angular speed of the platform after the event. Then Since the velocity of the ball is tangential to edge of the platform, the angular velocity of the ball is when the boy catches the ball and thus the angular momentum of the ball is.

By conservation of angular momentum this is equal to , the final angular momentum of the system. Suppose the platform of the previous problem is brought to rest with the ball in the hand of the kid standing on the rim. The kid throws the ball horizontally to his friend in a direction tangential to the rim with a speed as seen by his friend.

Find the angular velocity with which the platform will start rotating. Since the velocity of the ball is tangential to the edge of the platform, the ball has a linear momentum m when the boy throws it. The angular momentum of the ball when it leaves the boys hand is.

Suppose the platform with the kid in the previous problem is rotating in anticlockwise direction at an angular speed. The kid starts walking along the rim with speed relative to the platform also in the anticlockwise direction.

Find the new angular speed of the platform. Let be the final angular speed of the platform. Since the kid and the platform are moving in the same direction the angular speed of the kid relative to ground is. By the conservation of the angular momentum we have A uniform rod of mass and length is struck at an end by a force F perpendicular to the rod for a short time interval. Calculate a the speed of the center of the mass, b the angular speed of the rod about center of mass, c the kinetic energy of the rod and d the angular momentum of the rod about the center of mass after force has stopped to act.

Assume time t is so small that the rod does not appreciably change its direction while the force acts. Then The torque produced by the force F while it acted on one end of the rod is c b Since the rod undergoes both rotation and translation motion, the kinetic energy is given by.

The angular momentum is given by. A uniform rod of length L lies on a smooth horizontal table. If he stays on the ladder at a point 8. What should be the minimum coefficient of friction for the elctrician to work safely?

Find the maximum weight of a mechanic who could go up and do the work from the same position of the ladder. A 60 kg man stands half way up the ladder. The door is supported by two hinges situated at a distance of 1 ft from the ends. If the magnitudes of the forces exerted by the hinges on the door are equal, find this magnitude. Find the friction coefficient between the ground and the lower end if the minimum angle that the rod can make with the horizontal is O.

Calculate a the angular momentum of the rod about the axis of rotation, b the speed of the centre of the rod and c its kinetic energy. Calculate the angular momentum and the kinetic energy of the plate at the end of the fifth second after the start.

The system rotates at an angular speed co about an axis through the centre of mass of the system and perpendicular to the rod. An impulsive force of average magnitude 5.

Find the new angular velocity of the system. It picks up a stationary particle of mass g at its edge. Find the new angular speed of the wheel. If he folds his hands and feet to decrease the moment of inertia to 5.

Two heavy balls form part of the revolving system and the boy can pull the balls closer to himself or may push them apart. The boy holds an open umbrella in his hand.

The axis of the umbrella coincides with that of the platform. Find the angular velocity imparted to the platform. Find the moment of inertia of the second wheel.

The moment of inertia of the platform is I. The system is at rest when a friend throws a ball of mass m and the kid catches it. If the velocity of the ball is v horizontally along the tangent to the edge of the platform when it was caught by the kid, find the angular speed of the platform after the event. The kid throws the ball horizontally to his friend in a direction tangential to the rim with a speed v as seen by his friend.

Find the angular velocity with which the platform will start rotating. The kid starts walking along the rim with a speed v relative to the platform also in the anticlockwise direction.We want every student to get an equal opportunity to compete the entrance exam and become equal to those with high IQs and intelligent students.

A uniform square plate of mass 2 kg and edge 10 cm rotates about one of its diagonals under the action of a constant torque of 0. A A 10N?

Consider the two particles at the position 49 cm and 51 cm. Find the new angular speed of the wheel. Area under the curve will decide the total angle rotated? The book comes supplemented with a large number of solved and unsolved problems. Then by conservation of agular momentum we have. Suppose the platform of the previous problem is brought to rest with the ball in the hand of the kid standing on the rim.

Solution : A rod of mass m and length L, lying horizontally, is free to rotate about a vertical axis passing through its center.
