Sorry, not gonna do your homework for you.

Can you give me some hint by step by step for solving these questions?

I don't want to get the answers and I want to know how to do and solve its.

 

Thanks a lot.

As these question are straight application of the course, I'm not going to tell more neither.

Just that for the rivet, shear strength isn't necessarily the limiting factor. Bending stress uses to be much worse, especially for a hard dowel.

Stress = Load / Area

 

Strain = E * Stress

 

Those two equations, properly applied give you the second two problems.
