A grinding wheel is a uniform cylinder with a radius of 8.25 cmcm and a mass of 0.400 kgkg . Part A. Calculate its moment of inertia about its center. Part B. Calculate the applied torque needed to accelerate it from rest to 1700 rpmrpm in 4.50 ss if it is known to slow down from 1750 rpmrpm to rest in 55.5 ss .
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.
