Tension and torque equation
WebThe industry practice has been to measure the amount of torque required to tighten the bolt, and then attempt to relate that torque to tension. A “short form” equation for converting between torque and tension has been developed: T = K×F×D. where T is the torque measurement, K is the nut factor, F is the tension and D is the bolt diameter. Web2 Sep 2024 · Exercise 2.3. 7. A composite shaft 3 ft in length is constructed by assembling an aluminum rod, 2 in diameter, over which is bonded an annular steel cylinder of 0.5 in wall thickness. Determine the maximum torsional shear stress when the composite cylinder is subjected to a torque of 10,000 in-lb. Exercise 2.3. 8.

WebTorque and Tension in Bolts. Bolt, one of the most widely used fasteners in the industry, is usually tightened by applying torque to the head and/or nut. As the bolt is tightened, it is stretched (preloaded). Preload tension is necessary to keep the bolt tight, increase join strength, create friction between parts, and improve fatigue resistance. WebThe breakdown of torque usually shows that only 10% of the input torque is useful. The rest is used up by friction. For example, underhead torque represents 50% of the input torque and thread torque is 40%. Hence, the torque tightening process is not very efficient. This portion can be increased by applying a low friction lubricant.

WebDue to preload uncertainty, the actual preload applied to the bolt may be more or less than the nominal value. Due to preload relaxation, there will be some loss in the preload after the joint is installed. The maximum value of preload accounts for the preload uncertainty, and is calculated as: F PL.max = (1 + % uncrt ) · F PL.nom =.
WebThe second equilibrium condition (equation for the torques) for the meter stick is. τ 1 + τ 2 + τ + τ S + τ 3 = 0. When substituting torque values into this equation, we can omit the torques giving zero contributions.
