Bending Moment using Strain Energy Formula Elements

Variables
Functions
Bending Moment
The Bending Moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.
Symbol: M
Measurement: Moment of ForceUnit: kN*m
Note: Value can be positive or negative.
Strain Energy
Strain Energy is the energy adsorption of material due to strain under an applied load. It is also equal to the work done on a specimen by an external force.
Symbol: U
Measurement: EnergyUnit: N*m
Note: Value can be positive or negative.
Young's Modulus
Young's Modulus is a mechanical property of linear elastic solid substances. It describes the relationship between longitudinal stress and longitudinal strain.
Symbol: E
Measurement: StressUnit: MPa
Note: Value can be positive or negative.
Area Moment of Inertia
Area Moment of Inertia is a moment about the centroidal axis without considering mass.
Symbol: I
Measurement: Second Moment of AreaUnit: m⁴
Note: Value should be greater than 0.
Length of Member
Length of Member is the measurement or extent of member (beam or column) from end to end.
Symbol: L
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
sqrt
A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number.
Syntax: sqrt(Number)
