Question

The collar at B slides along the circular bar, causing pin B to move at constant speed in a circular path of radius r. Bar BC slides in the collar at A. At the instant shown, determine the angular velocity and angular acceleration of B.

a) Angular velocity of B: ______
b) Angular acceleration of B: ______

Answer 1

The angular velocity of B can be found by calculating the change in angular position divided by the change in time. The angular acceleration of B can be found by calculating the change in angular velocity divided by the change in time.

Step-by-step explanation:

The angular velocity of B at the instant shown can be determined by finding the rate of change of the angular position of B with respect to time. In this case, we are not given the specific values for the radius or the time, so I will provide a general formula.

The formula for angular velocity is given by:

Angular velocity = change in angular position / change in time

To find the angular acceleration of B, we need to differentiate the angular velocity with respect to time. In other words, we need to find the rate of change of the angular velocity.

The formula for angular acceleration is given by:

Angular acceleration = change in angular velocity / change in time
