a$)$ Design an electro$-$hydraulic circuit in FluidSim to perform the machine cycle, initiated by a single push$-$button. Cylinders A and B are used for the clamping system, while Cylinder C is used for the stamping operation. Add flow control to the cylinders $($either meter$-$in or meter$-$ out$)$ and explain the rationale behind your chosen flow control method.

b$)$ Draw the step diagram of cylinders A$,$ B$,$ C$,$ and D$,$ along with their associated sensor $($switch$)$ signals.

c$)$ Modify Cylinder D to include a Free Fall Prevention feature.
