Hello, I think I did this correctly, and I would just check but I'm running out of submissions for my homework so a quick varification would be greatly appreciated. Here's the problem: The drawing shows the blade of a chain saw. The rotating sprocket tip at the end of the guide bar has a radius of 4.3x10^-2m. The linear speed of a chain link at point A is 8.9 m/s. Find the angular speed of the sprocket tip in rev/s. http://www.webassign.net/CJ/08_63.gif]Drawing [Broken] So I just assumed I could use this equation to solve for the problem. V_T = rw 8.9 = 0.043(w) 8.9 = 0.043w 206.98 = w That seems really fast to me. But the section about this sort of problem in my book is extremely small and has no examples to follow. So I'm not sure what else I would need to be doing. Thanks in advance for any help that is provided.
