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.
a) A 3.00-m-long, 290 N, uniform rod at the zoo is held in a horizontal position by two ropes at its ends in (Figure 1). The left rope makes an angle of 150∘ with the rod and the right rope makes an angle θ with the horizontal. A 90 N howler monkey (Alouatta seniculus) hangs motionless 0.50 m from the right end of the rod as he carefully studies you.
a) Calculate the tension in the left rope.
b) Calculate the tension in the right rope.
c) Calculate the angle θ.
