DEflection
Deflection (∆ Max) is essentially the measure of how much an object flexes when a load is applied. An objects stiffness is measured in moment of inertia, or Ixx.. The modulus of elasticity, or E (psi), is the materials ability to stretch.
Moment of Inertia = Ixx= (b*h3)/ (12)
Deflection = ∆max = (F*L3)/ (48*E*I)
Modulus of Elasticity = E = (F*L3)/ (48*I*∆max)
We can use deflection to meausure the force applied to the object.
To do this we need to know several variables:
b= the width of the base of an object
h= the height of the side of the object
L= the span of the object in between two supports
Dpl= preloading distance or the distance from the bottom of the object to an object below it without any weight on it.
∆max= difference in the measurements Dpl and after the load is applied
F= force applied to the object (what we're solving for)
E= modulus of elasticity
I= moment of inertia
After assembling all of those numbers we need to plug all the knowns into the equation: F= E * [(48*I*∆max)/(L3)].
The answer to that equation will be the force applied to the object. This equation can be manipulated to find any of the variables in it.
