See attached picture. Two forces are exerted on a rod that is free to rotate about an axis at its end. One force is exerted at the other end of the rod and the second force is exerted at the center of the rod. If the rod is 3.0 ft long, find the magnitude of the net Torque experienced by the rod. a) 13.2 ft. lbs. (foot pounds) b) 27.7 ft. lbs. c) 30.6 ft. lbs. d) 132 ft. lbs.
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.
