Locate one point about which the particles angular momentum is constant and another about which it changes with time.

This result is valid only when p V. For example, when divers wish to double their angular speed, they must reduce their moment of inertia to one-half its initial value.

A light, rigid rod 1.

Facing the axle, a The platform has a mass M kg and a radius R 2. A feedback mechanism senses the angular speed of the disk, and a drive motor at Equilibrip ensures that the angular speed remains constant.

In other words, when the linear velocity of the particle is along a line that passes through the origin, the particle has zero angular momentum 90with respect to the origin. In these cases, the external force due to equklibrio acts through the center of mass and hence exerts no torque about this point.

The two forces acting on the top are the downward force of gravity Mg and the normal force n acting upward at the pivot point O. The total angular momentum of the precessing wheel is the sum of the angular momentum I due to the spinning and the angular momentum due to the motion ofPrecessional motionz LCM n Mg r O x a yL Li Lf b Precessional motion of a top spinning about its symmetry axis.


In this case, the moment of inertia cannot be treated as a scalar. In this case we express the conservation of angular momentum in the form Li Lf constant A spool of wire rests on a horizontal surface as in Figure P A solid cube of side 2a and mass M is sliding on a frictionless surface with uniform velocity v, as shown in Figure P This torque causes the angular momentum to change in the direction perpendicular to the axle. Assuming energy conservation, calculate the moment of inertia of the can if it takes 1.

What can you conclude about the direction of its angular momentum vector with respect to the direction of motion?

When a cylinder rolls on a horizontal surface as in Figure Let us consider the torque acting on the wheel about the pivot O.

Movimiento Rotacional y Angular Documents. Se denominan sistemas de referencia no inerciales. It does not roll off the top end. A particle is moving in a circle with constant speed.

11-Movimiento Rotacional y Momento Angular

hraslacional What is the new angular speed of the merry-go-round? For angular momentum to be conserved, some other part of the system has to start rotating so that the total angular momentum remains the initial angular momentum L i.


Solutionmass givesNewtons second law applied to the center ofwhere x is measured along the slanted surface of the incline.

State the quantities you take as data, the values you measure or estimate for them, and your reasoning. A metal can containing condensed mushroom soup has a mass of g, a height of In general, such motion is very complex.

The net external torque acting on a particle or rigid object is equal to the time rate of change of its angular momentum: Because the net force is not necessarily zero, you cannot conclude that the particles velocity is constant.

Determine the particles angular momentum when its position vector is r 1. The length of the agpole isand is the angle the agpole makes with the horizontal.

Equilibrio de Rotación – Problema 03

This is an excellent eqiulibrio of the importance of the directional nature of angular momentum. A thin rod with a mass of 0. Therefore, like the torque vector, d L must also be at right angles to L.
