In an engine, a 7-inch connecting rod is fastened to a crank of radius 3 inches. The clankshaft rotates counterclockwise at a constant rate of 200 revolutions per minute. Find the velocity of the piston when [tex] \theta = \frac{\pi}{3} [/tex].(adsbygoogle = window.adsbygoogle || []).push({});

I know that I have to use the Law Of Cosines. However I am unclear about the question.

Any ideas and help are appreciated

Thanks
