What equation for acceleration? Polar Determine r dot and r double dot. Determine θ dot and θ double dot. 0 = θ Determine values at 30 degrees Substitute values into acceleration equation Could transform this into Cartesian coordinates – try to do this For the mechanism shown at right, the slotted bar rotates
