Cantilever Beam Stiffness
- The stiffness, kz, of a cantilever beam is a measure of its resistance to deflection in the vertical (z) direction.
- It is often referred to as the spring constant.
kz = \(\frac{Eab^3}{4l^3}\)
kz = (\frac{Eab^3}{4l^3}\)
Where:
E = young's modulus of the material
a = the beam width
b = beam thickness
l = beam length
Normal Load:
- The normal load, FN, applied at the free end of a beam is calculated using Hooke's law:
FN = kz Δz
Where:
Δz = vertical deflection distance
