Stiffness is resistance to deflection.
Stiffness is the resistance of an elastic body to deflection or deformation by an applied force - and can be expressed as
k = F / δ (1)
k = stiffness (N/m, lb/in)
F = applied force (N, lb)
δ = extension, deflection (m, in)
Forces, acceleration, displacement, vectors, motion, momentum, energy of objects and more.
Loads - forces and torque, beams and columns.
Stress, deflections and supporting loads.
Supporting loads, stress and deflections.
Maximum reaction forces, deflections and moments - single and uniform loads.
Calculate buckling of columns.
Elastic properties and Young's modulus for metals and alloys like cast iron, carbon steel and more.
Shear Modulus (Modulus of Rigidity) is the elasticity coefficient for shearing or torsion force.
The torsion of solid or hollow shafts - Polar Moment of Inertia of Area.
Support reactions and bending moments.
Young's Modulus (or Tensile Modulus alt. Modulus of Elasticity) and Ultimate Tensile Strength and Yield Strength for materials like steel, glass, wood and many more.
