Leaf Springs Calculator  

Where,
E = Youngs modulus [Nm^{2}]
n = Number of Leaves
b = Width of leaves [m]
t = Thickness of leaves [m]
L = Spam [m]
Example:
Calculate the Stiffness of the leaf spring for the given details.
Youngs Modulus (E): 25 mW
Number of Leaves (n): 15
Span (L): 10 cm
Width of Leaves (b): 5 mW/cm^{2}
Thickness of Leaves (t):20 mW/cm^{2}
Solution:
Apply Formula:
k = 8Enbt^{3}/3l^{3}
k = 8*25*15*5*20^{3} / 3*10^{3}
k = 15000*8000/3*1000
k = 120000/3000
k = 40000 mW/cm^{2}
Stiffness (k): 40000 mW/cm^{2}
