# Deflection Due to Thrust Calculator

Posted by Dinesh onUse this simple rock movements calculation tool helps to compute the deflection due to thrust 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: `?`

.^{'} = (H * K_{2}) / (E_{r})

## Deflection Due to Thrust - Rock Movements Calculation

### Formula:

?^{'} = (H × K_{2}) / (E_{r})

- H - Arch thrust
- K
_{2}- Poisson’s ratio constant - E
_{r}- Elastic modulus of the rock - ?
^{'}- Deflection due to thrust
