Calculation of reactions

For statically determinate system rcaction is calculated using the cquilibrium Conditions and design conditions. For a fiat system, there are three conditions of cquilibrium. giving risc to three cquations:

•    Projection of forces on the Y axis

•    Projection of forces on the X axis

•    The sum of all moments occurring in the system

The aniculnted design should also remember that the sum of the moments on the leli and right sidc equa! to 0.
