38. Problem 13.2E (HRW) A certain nut is known to require forces of 40 N
exerted on its shell from both sides to crack it. What force component
|
,
perpendicular to the handles, will be required when the nut is placed in the
nutcracker?|

As the nut breaks when a force of 40 N is applied on it from each side, force
|
will have
to be applied at ends of each handle in order that a force of 40 N develops on
the nut. This force will develop because the torque about the joint of the
nutcracker has to be zero.
