1. An apparatus for calibrating a shear test tool, the apparatus comprising:
a fixed element,
a pivotable element configured to be rotatable relative to the fixed element, and
a resilient pivot mechanism disposed between the fixed element and the pivotable element and coupled to both the fixed element and the pivotable element to form a pivot such that the pivotable element is rotatable about the pivot to lift a weight coupled to the pivotable element when the shear test tool applies a force on the pivotable element in order to rotate the pivotable element and lift the weight.
