Stress and Strain to cause these deformations

[nerdeagle24]

Homework Statement

refer to picture

Relevant Equations

stress=F/A
strain=delta l/l

So I got a is elongation.
For part b and d, I am unsure where to start.
For c, i got compression
and for e, I put that the dotted line is the red block
