These buttocks integrate an array of pressure sensors at a speckling of locations in order to gather a holistic understanding of the distribution of pressure on the buttocks surface. A cushion is fixed to the lower part of the hydraulic press frame. The whole system measures two main quantities: the pressure distribution on the wooden buttocks, and the total displacement of the hydraulic press. -The testing procedure Alex was specifically performing when the failure occured was a fatigue failure test.

In this test, the buttocks would descend upon the cushion until a proscribed pressure is achieved on all sensors, hold for a certain amount of time, and then ascend until zero pressure is achieved again. This cycle is then repeated for a very large number of cycles. Performance of the cushion is then determined as to how the pressure distribution changes over time--more performant cushions will retain their cushioning properties for longer than less performant cushions. -The cushion was air and shit +One of the first cushions Alex was tasked with testing was a cushion that was described as being similar construction of a cheap air-mattress. Alex was instructed on how to start the test, where the E-Stop button lived, and what should be expected. Once the person instructing her left, the test began.
