Homework Statement
Find the aceleration of each link in the mechanism
Relevant Equations
W = V´2/r
Hi guys!
I have problems with this mechanism...finding the aceleration with graphic method.

I already have drawn the speed diagram and the values of all of them.

But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the acceleration of "G"

Thank you.
Could you show us your work on velocities?
 

1. How do I calculate acceleration using the graphic method?

To calculate acceleration using the graphic method, you need to plot the velocity vs. time data on a graph and find the slope of the line. The slope of the line represents the acceleration.

2. What is the difference between average acceleration and instantaneous acceleration?

Average acceleration is the change in velocity over a specific time interval, while instantaneous acceleration is the acceleration at a specific moment in time. In other words, average acceleration is an average over a period of time, while instantaneous acceleration is a specific value at a specific point in time.

3. Can I use the graphic method to calculate acceleration for non-uniform motion?

Yes, the graphic method can be used to calculate acceleration for both uniform and non-uniform motion. However, for non-uniform motion, you will need to find the slope of the tangent line at a specific point on the graph to determine the instantaneous acceleration.

4. What are some advantages of using the graphic method to calculate acceleration?

One advantage of using the graphic method is that it provides a visual representation of the data, making it easier to understand and interpret. Additionally, it can be used for both uniform and non-uniform motion, and it does not require complex mathematical calculations.

5. Are there any limitations to using the graphic method for acceleration calculations?

One limitation of the graphic method is that it may not be as accurate as other methods, such as calculus, for calculating acceleration. Additionally, it may be difficult to obtain precise measurements from a graph, which can affect the accuracy of the calculated acceleration.
