## Inputs ##

H = Key's Hight
W = Key's Width
L = Key's Lenght
N° = number of Keys
Di = Hub's Internal Diameter
De = Hub's External Diameter
Ys = Shaft Yield Stress
Yh = Hub Yield Stress
Yk = Key Yield Stress
T = Applied Torque

## Outputs ##

τ Shear = Key's Shear Stress
ς Press = Average Contact Pressure between Key, Shaft and Hub
σ Hub = Max Hub Stress
