In the figure below a crowbar is used to lift a weight. If a down ward force of 246 N is applied to the end of the bar, how much weight does the other end bear? The crowbar itself has negligible weight. (Let r1 = 30.5 cm and r2 = 4.70 cm.) please sovle thank you
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.
