Select all the correct statements related to the elastic$/$ plastic working regions.

It a part is loaded to the plastic deformation region, it will keep its deformed shape as it is when it is unloaded.

Design engineers would like the part not fail $($rupture$)$ even though it anay ga into plastie regian under operational loads

If the warking temperature increases, yield strength will increase.

The part shows plastic defarmation ance the load creates a stress mare than the yield strength

Manufacturing processes take place in the plastic region

Parts are designod to work in elastic region of stress$-$strain curve
