Book Question -- velocity polygon and corelis acceleration

In summary, the conversation discusses the concept of velocity polygon and Coriolis acceleration in relation to mechanism problems. The idea is that velocity relations can be expressed as a closed polygon, and the Coriolis acceleration is a natural result of this approach.

Can someone please tell me what book is about velocity polygon and corelis acceleration?

Thank you

By "velocity polygon" are you referring perhaps to how it can sometimes look like a polygon when drawing out the addition of two vectors?

Perhaps the OP is referring to the idea that, in many mechanism problems, it is convenient to express position relations in terms of a polygon that remains closed at all times, although it may deform as parts move and time passes.

When these relations are differentiated with respect to time, the result is a closed polygon of velocity vectors.

The Coriolis acceleration falls out naturally wherever it is relevant with this approach to kinematics.
 

1. What is a velocity polygon?

A velocity polygon is a graphical representation of the velocity of different points in a mechanism or machine. It is formed by drawing line segments from each point to represent its velocity and connecting them to form a closed polygon.

2. How is a velocity polygon different from a velocity vector diagram?

A velocity polygon shows the relative velocities of different points in a mechanism, while a velocity vector diagram shows the actual velocities of these points. Additionally, a velocity polygon is a closed figure, while a velocity vector diagram is an open figure.

3. What is the purpose of constructing a velocity polygon?

The main purpose of constructing a velocity polygon is to analyze the motion of a mechanism or machine and determine the relative velocities of its different parts. This can help in understanding the functionality of the mechanism and identifying any potential issues.

4. How is corelis acceleration related to a velocity polygon?

Corelis acceleration is the rate of change of velocity in a mechanism. It can be calculated by differentiating the velocity polygon. Therefore, the velocity polygon is a useful tool in understanding corelis acceleration and its effects on a mechanism.

5. Can a velocity polygon be used to determine the acceleration of a mechanism?

Yes, a velocity polygon can be used to determine the acceleration of a mechanism. By differentiating the velocity polygon, the acceleration polygon can be constructed, which represents the acceleration of different points in the mechanism. This can provide valuable insights into the performance of the mechanism and potential areas for improvement.
