12. ROLLING, TORQUE AND ANGULAR MOMENTUM
A single force F acts on the particle and the angle between the force and the position vector is [phi]. Per definition, the torque exerted by this force on the mass, with respect to the origin of our coordinate system, is given by. and. where r[invtee] is called the arm of the force F with respect to the origin.

Centripetal force problem solving (video) | Khan Academy
These forces do not point inward toward the center of the circle. The only force in this case that points toward the center of the circle is the tension force, and like we already said, that is the centripetal force. So over here, I'd have v squared over r, and that would equal the only force acting as the centripetal force .

Rotation: Moment of Inertia and Torque Maplesoft
Torque, also known as the moment of force, is the rotational analog of force. This word originates from the Latin word torquere meaning "to twist". In the same way that a force is necessary to change a particle or object's state of motion, a torque is necessary to change a particle or object's state of rotation.

Groove rolling. A distinction must be made between rolls with different grooves (e. g. in blooming mills) and rolls with identical grooves (e. g. in wire mills). In rolls with different grooves, a pass schedule should be calculated indicating the time percentages and the rolling forces in the individual grooves.

Rotation and WorkEnergy Principle
WorkEnergy Principle. The workenergy principle is a general principle which can be applied specifically to rotating objects. For pure rotation, the net work is equal to the change in rotational kinetic energy:. For a constant torque, the work can be expressed as. and for a net torque, Newton's 2nd law for rotation gives Combining this last expression with the workenergy principle gives a ...

The rolling constraint is formulated setting up the velocity of the contact point instantaneously equal to zero, and expressing it as the velocity of the center of mass rθ˙, plus the velocity with respect to the center of mass, aφ˙. The equivalent condition for the hoop rolling on a plane is ˙x+aφ˙ = 0.
