Hello thanks a lot for sharing this information... I was stuck on permanent strain so i decided to check it up and your video popped up first.. Its very helpful and educative. Keep it up

Putting this here so it shows up on Google better:

If the bolt is made from a material having a shear stress–strain diagram that is approximated as shown in the figure below (Figure 2), determine the permanent shear strain in the shear plane of the bolt when the applied force P = 130 kip is removed.

Should we not use double shear stress for this one?
