Young's Modulus (E)
"Young's modulus or modulus of elaticity (and also elastic modulus) is a measure of the stiffness of a given material. It is defined as the limit for small strains of the rate of change of stress with strain."*

Moment of Inertia (I)
"Moment of inertia quantifies the resistance of a physical object to angular acceleration. Moment of inertia is to rotational motion as mass is to linear motion."*

Total Length (L)
Total length is the overall length of the beam under consideration.

Return to Calculator
Partial length (a)
Partial length (a) is the distance from one point of reference to another, usually being how far a force is applied from an end of the beam.

Return to Calculator
Partial length (b)
Partial length (b) is the distance from one point of reference to another, usually being how wide of an area a force is being applied or the distance from a second end to the force being applied complimentarily with partial length (a).

Point Load (P)
Point load (P) is a force applied at a single infinitismal point at a set distance from the ends of the beam.

Return to Calculator
Uniform Distributed Load (q)
Uniform distributed load (q) is a force applied over an area, denoted by q which is force per unit length.

Applied Moment (M#)
Applied moment (M) is a force couple that creates a torque, a twisting force, at a point along the beam.

Maximum Deflection (y)
Maximum deflection (y) is the greatest distance the end of the beam could move up (+) or down (-) when a load of the specified magnitude is applied to the beam.

Return to Calculator
End Slope (θx)
End slope (θ) is the angle that the beam makes at the end after it is deflected by the load.
