## Description ##
This app calculates the Shear Stress, Contact Pressure and the Max Stress in Shaft Keyed Joint. By default, a Safety Factor below 1.1 is marked red, above 1.1 green.
H = Keys Hight
W = Keys Width
L = Keys Lenght
N° = number of Keys
Di = Hubs Internal Diameter
De = Hubs External Diameter
Ys = Shaft Yield Stress
Yh = Hub Yield Stress
Yk = Key Yield Stress
T = Applied Torque
τ Shear = Keys Shear Stress
ς Press = Average Contact Pressure between Key, Shaft and Hub
σ Hub = Max Hub Stress
