2. T HE E XPERIMENT We are to apply a quasi-hydrostatic pressure on a 6” diameter pipe. 2 Figure 1 – Sketch Pipe under hydrostatic pressure

3. T HE D ESIGN P ROCESS Figure 2 – Transverse cross section of the pipe being compressed by six sections 3 Outer Ring Hydrostatic Press Spacing (incompressible media) Pipe

5. T HE PROBLEM : 5 The strongest actuators that can accommodate our budget are not nearly as strong as our calculations assumed Our sponsor advised that we should design around the actuator’s force
