Can a tensioned bolt return to its original shape?
Can a tensioned bolt return to its original shape?
Thus, a bolt that is properly tensioned should be functioning in the elastic range (as viewed on the Diagram). If the load is removed and the fastener is still within the elastic range, the fastener will always return to its original shape. However, if the load applied causes the fastener to exceed its yield point , it enters the plastic range .
What causes soreness and tenderness in the body?
Cellulitis, a bacterial infection of the skin, causes red, tender skin that is usually swollen and warm. Bruises, or contusions, cause skin discoloration, swelling and tenderness. Exercise is vital for good health, but overdoing it can lead to muscle aches, dehydration, headache, and more.
What should be the shear strength of a bolted joint?
shear plane. When no shear strength is given for common carbon steels with hardness up to 40 HRC, 60 % of the ultimate tensile strength of the bolt is typically used as acceptable shear strength. Note: the shear strength must fall within the constraints of a suitable safety factor. This formula should only be used as an estimation.
What happens if there is too much clamping on a bolt?
With too little clamping force, the joint may loosen. If the joint is exposed to cyclical loads, too little clamping force can shorten the bolt’s fatigue life. Too much clamping force can also cause severe problems. By over-tightening the bolt, one may exceed the proof load of the bolt.

When to see a doctor for abdominal tenderness?
A doctor may apply pressure to the abdomen to help diagnose the cause of tenderness. Appendicitis occurs when a person’s appendix becomes inflamed. The appendix is a small pouch linked to the large intestine. It is not yet clear whether it has a function, or what that function might be. Symptoms of appendicitis include:
