 BELOW IS MY ANSWER TO THE QUIZ

 

 

 

 

 

 

 

 

Mu is the coefficient of friction static=dynamic

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

(without Mu)

Re: QUIZ: wire bending

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

47N x 2 (?)

Oops again.
