Solution of problem 9.2.5 from the collection of Kepe O.E.

9.2.5 It is necessary to calculate the angular speed of rotation of the wheel if point A on its circumference has a speed vA = 2 m/s, and the radius of the wheel is r = 1 m. (Answer 1.79)

To solve this problem, it is necessary to use the formula for the connection between linear and angular velocities for a point on a circle: v = rω, where v is the linear velocity, r is the radius of the circle, and ω is the angular velocity.

From the conditions of the problem vA and r are known. Substituting them into the formula, we get: vA = rω. Resolving the equation for ω, we obtain: ω = vA / r.

Substituting the known values, we get: ω = 2 / 1 = 2 rad/s. The answer must be rounded to two decimal places: 1.79 rad/s.

Problem 9.2.5 from the collection of Kepe O.?. consists in determining the angular speed of the wheel if the speed of point A and the radius of the wheel are known. To solve this problem, it is necessary to use the relationship between linear and angular velocity, which looks like this:

v = r * ω

where v is the linear speed, r is the radius of the wheel, and ω is the angular speed.

Based on this relationship, you can determine the angular speed of the wheel by substituting known values ​​into the formula:

ω = v / r

In this case, the speed of point A is 2 m/s, and the radius of the wheel is 1 m. Substituting these values ​​into the formula for determining the angular speed, we get:

ω = 2 / 1 = 2 rad/s

Answer: The angular speed of the wheel is 2 rad/s, which corresponds to a rounded value of 1.79.
