THE EXPERIMENT We are to apply a quasi-hydrostatic pressure on a

6” diameter pipe.

THE 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

REPLACING ACTUATORS BY STATIONARY

COLUMNS

15

COLUMNS ARE CHARACTERIZED BY IT’S SLENDERNESS

RATIO

L = LENGTH OF THE COLUMN

K = RADIUS OF GYRATION

Page 16: The CRUSHED Experiment

If the Slenderness Ratio < 10 The column is now bound by the Mechanical

Properties To ensure this:

L = 1.94 inch same length as hydraulic cylinders

Diameter > 0.776 inch Diameter is set to be 1 inch Made out of structural steel ASTM - A36

Same as I-beams
