Each of the bars, A and B, is in contact with its respective wheel rim without slipping. The smaller wheel has a radius of r = 0.108 m and the larger wheel has a radius of R = 0.164 m. The two wheels are attached to each other and rotate as a unit. At the instant shown, bar B has a velocity of = 4 m/s (towards the right) and an acceleration of = 3 (towards the left). Bar A is fixed. What is the acceleration (in ) of point C on the rim of the smaller wheel at this instant? Choose the correct answer.
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.
