(a) Draw a sketch (which will be used in the FluidSIm software) the design and assembly of the Hydraulic Circuit for the drive (fixing and working) of a drill, with the following characteristics:
- Sequential operation, put pressure, for advance and return of the cylinders (according to the proper operation for the device) controlled by a directional 4x3 electric drive way;
(b) The circuit must provide for different speed ranges for drilling work so as to allow different materials to be treated.
Note: Set the safety valve to 55 bar.
