A cylinder with rotational inertia I1=2.0kgm2 rotates clockwise about a vertical axis through its center with angular speed 1=5.0rad/s . A second cylinder with rotational inertia I2=1.0kgm2 rotates counterclockwise about the same axis with angular speed 2=8.0rad/s . If the cylinders couple so they have the same rotational axis what is the angular speed of the combination? What percentage of the original kinetic energy is lost to friction?
A 95 N force is applied to the end of a .5 meter long torque wrench which gives a rise to a torque of 15 N*m. What is the angle between the wrench and handle? What is the direction of the force?
This week in lab you observed how a force can apply a torque and rotate an object. Using the concepts of applied force and torque, describe how a doorstop works to keep a door open. Where along the length of the door is the doorstop most effective? (That is, closer or farther from the hinges?) Explain your reasoning using the concepts of force and torque.
F Pivot d The length of the pool cue is 1.5 m. A force of 11 N is applied at an angle 55°, a distance 0.7 meters from the pivot. What is the torque created? Answer to 3 sig figs.
Two forces are applied to a merry-go-round with a radius of 1.5 m as shown in the diagram. One force has a magnitude of 150 N and the other a magnitude of 54 N. How much is the net torque acting on the merry-go-around? What is the direction of net torque? If the merry-go-round is accelerating rotationally at a rate of 0.45 rad/s2 determine its rotational inertia.
