Webb21 maj 2024 · F_AP = Axial Preload Force applied to the bolted joint K_T = Coefficient of Torque. The coefficient of torque is a calculation based on the condition of the fastener and can be affected by lubrication, plating, anti-seize compounds, etc. The coefficient of torque can be estimated as 0.2 if the condition is unknown. Example: WebbThe effort force for a screw jack when neglecting friction can be expressed as. F = (Q p) / (2 π R) (1) where. F = effort force at the end of the arm or handle (lb, N) Q = weight or load (lb, N) p = pitch - distance or lead of thread in one turn (in, m) R = lever-arm radius (in, m) The torque acting on the screw can be calculated as. T = F R (2)
