A machinist turns on the power on to a grinding wheel at time t=0s .the wheel accelerates unifrmly from rest for 10s and reaches the operating angular speed of 58rad/s. the wheel is run at that angular velocity for 30s and the power is shut off. The wheel slows down uniformly at 1.4rads/s^2 until the wheel stops. What is the total number of revolutions made by the wheel in this situation? a)510 b)470 c)280 d)320 e)750
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.
