Stress Test 'Overcut' Rafter to Failure

What happens here

The rafter piece labeled 'OVER CUT' is carefully positioned within the wooden testing frame. The hydraulic power jack is then activated and manually pumped to apply a steadily increasing upward force against the overcut rafter. While the exact pressure readings are not clearly visible in this segment, the gauge is observed to rise. The rafter piece begins to visibly bend and creak under the load before eventually failing with a distinct snapping sound, indicating its breaking point.

Goal: Determine the failure point of an 'overcut' rafter.
