Write net torque and net force equation for a simple seesaw system

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 975 lb of force to perform the press fit. The piston at the input cylinder is pushed with a force of 250 lb and has an area of 30 in.2. The output can use up to 15 cylinders that are each 30 in.2. How much mechanical advantage is required to gain the necessary force ?

why is the actual weight is lower than the theoretical weight
