Wrench Torque Formula
T= F x r
Torque= Force x Lever Arm Length
Ex.: 1000kN x 60mm= 60000 N.m
Bolt Load- Torque Formula
T= K x D x N
T: Torque
K: Friction Factor
D: Bolt O.D
N: Bolt extended Load= Stress area x Yield strength x Percent of Yield
Ex.: M16
μ= 0.10: Low friction application
μ= 0.15: Normal friction application
μ= 0.20: High friction application
