## Re: QUIZ: wire bending

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.

SOLVE TIME APPROXIMATELY 100 seconds.

Elements:              142

Contacts:         1

## Re: QUIZ: wire bending

very good

what about z=-100 mm? (oddly interesting effect)

## Re: QUIZ: wire bending

yes, I see a maxima around 85mm,  47N for Mu=0.3

Highlighted

(without Mu)

## Re: QUIZ: wire bending

"... 47N for Mu=0.3..."

47N x 2 (?)

Oops again.
