What happens here
With the setup verified, begin operating the hydraulic pump. This involves repeatedly actuating the pump lever to gradually increase the pressure within the hydraulic system. Closely monitor the pressure gauge as the force builds. The hydraulic ram will extend, exerting a progressive load onto the 'DECK Screw' and its surrounding wooden structure. Continue applying force until a definitive failure occurs, which will likely be accompanied by an audible sound (like snapping or splintering) or visible deformation. The video demonstrates this action, showing the pump being operated and the pressure gauge increasing until failure, at which point text appears indicating 'Failed Test' and the recorded failure load of '4ton'.
Goal: Apply pressure until the deck screw or its connection fails, and record the failure load.
Tools and materials
- Hydraulic Pump with Pressure Gauge — To generate controlled force and measure the applied pressure during the test
- Hydraulic Ram — To apply the compressive force to the test setup until the deck screw fails
- Wooden Testing Frame — To hold the deck screw in place and react to the force applied by the hydraulic ram
