Use this simple rock movements calculation tool helps to compute the deflection due to shear for your hydraulics and waterworks problems. If the ends of the arch elements are vertical, and the bases of the cantilever elements, horizontal, rock rotations and deflections of elements with parallel sides 1 ft apart may be calculated by the formula: γ' = (V * K3) / (Er).

Values of K Constants in Eqs. (12.193) to (12.198) for Poisson’s Ratio = 0.20
