BELOW IS MY ANSWER TO THE QUIZ
Mu is the coefficient of friction static=dynamic
Contacts, prismatic elements, and left end constraint "in plane"
Right end constraint for symmetry and enforced displacment.

very good
what about z=-100 mm? (oddly interesting effect)
yes, I see a maxima around 85mm, 47N for Mu=0.3
(without Mu)
"... 47N for Mu=0.3..."
47N x 2 (?)
Oops again.
