Crankshaft A crank of radius r rotates with an angularfrequency w. It is connected to a piston by a connecting rod oflength L (see figure). The acceleration of the piston varies withthe position of the crank according to the functionr cos 20a(0) = wr( cos 0 +LFor fixed w, L, and r, find the values of 0, with 0 = 0 = 27, forwhich the acceleration of the piston is a maximum and minimum.CrankConnecting rodPistona
