How to calculate the work done during rotational motion?
Calculate the work done during the body’s rotation by every torque. Apply the work-energy theorem by equating the net work done on the body to the change in rotational kinetic energy. Let’s look at two examples and use the work-energy theorem to analyze rotational motion.
What is the average delay of a rotation?
Because any delay in this range is equally likely, the average delay is simply half of a rotation. When dealing with multiple disks, however, this simple model no longer works. This is because the rotational delay we experience is bounded by the longest delay incurred by any of the disks.
How much rotational energy does a grindstone have?
A uniform cylindrical grindstone has a mass of 10 kg and a radius of 12 cm. (a) What is the rotational kinetic energy of the grindstone when it is rotating at (b) After the grindstone’s motor is turned off, a knife blade is pressed against the outer edge of the grindstone with a perpendicular force of 5.0 N.
How does a pulley work on the rotational axis?
, the weight of the pulley, exerts a torque around the rotational axis, and therefore does no work on the pulley. As the pulley rotates through an angle If the force on the string acts through a distance of 1.0 m, we have, from the work-energy theorem, Power always comes up in the discussion of applications in engineering and physics.
How to calculate the rotation of the x axis?
Direct link to newbarker’s post “You could find 3 separate transformation matrices …” You could find 3 separate transformation matrices for each of the rotations and then multiply them together into one. If they were called tranX, tranY and tranZ, then they would need to be multiplied as follows: combined = tranZ * tranY * tranX.
What makes a disk rotate around a vertical axis?
A uniform disk of mass 500 kg and radius 0.25 m is mounted on frictionless bearings so it can rotate freely around a vertical axis through its center (see the following figure).
