Question

For the first nutcracker, two applied forces of magnitude f were required to crack the nut, whereas for the second, only one applied force of magnitude f was required. how would you explain this difference?

Answer 1

A) F = (F_n*d)/D

B) F = (F_n*d)/D

C) There is an additional force of magnitude Fn applied to the nut by the fixed jaw in the second case. This jaw is held fixed by external forces (such as the forces due to the frame).

Step-by-step explanation:

This is the right answer, trust me. I got it wrong bc of the other moron who wrote that "tutor approved" answer. I hope you see this MORON.

_ = subscript

p.s. It's the same thing for both part A and B
