A massless rope exerts a force on the edge of a pulley as shown below. The pulley is a solid disk with a mass of 1.20 kg and a radius of R=0.400 m. The angular acceleration of the pulley is observed to be 28.00 rad/s^2. (a) Determine the torque exerted on the pulley (b) Determine the magnitude of F. [If you do not have an answer for part a, use a torque of 2.00 Nm
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
