Elastic deflection of a center loaded beam supported by two simple supports.


In engineering, deflection is the degree to which a structural element is displaced under a load.
The elastic deflection of a beam, loaded at its center, supported by two simple supports can be calculated by by the force acting on the center of the beam, the length of the beam, the modulus of elasticity and the area moment of inertia.
