The Resultant Load on the Bolt GO

what is the difference between elongation and compression?

Deformation is the change in the shape or dimensions of a body under the application of load, whereas Elongation is the change in length of the body under the application of load. So elongation is a form of deformation, but deformation needs not just be elongation alone.

How to Calculate Amount of Compression in the Parts Joined by the Bolt?

Amount of Compression in the Parts Joined by the Bolt calculator uses compression in parts by bolts=pre-load/combined stiffness of bolt to calculate the compression in parts by bolts, Amount of Compression in the Parts Joined by the Bolt is the decrease in length of parts joined by bolt after the bolt is tightened. compression in parts by bolts and is denoted by c symbol.

FAQ

What is Amount of Compression in the Parts Joined by the Bolt?
Amount of Compression in the Parts Joined by the Bolt is the decrease in length of parts joined by bolt after the bolt is tightened and is represented as c=Pi/kc' or compression in parts by bolts=pre-load/combined stiffness of bolt. pre-load is defined as the load generated due to the wrench torque and combined stiffness of bolt is the final stiffness of the two bolts which is obtained from the formula of combinations of spring.
