A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 3453 lb. of force to perform the press fit. The piston at the input cylinder is pushed with a force of 723 lbs. and has an area of 33.7 in.2. The output can use up to 15 cylinders that are each 33.7 in.2.

How many output cylinders must be incorporated into the design?
