Part B

Using the $70\mathrm{.}1$ cm long wrench from Part A$,$ the bolt has now been unscrewed a length of $6\mathrm{.}00$ cm $.($Figure $2)$ The force of $F=\{-178\mathrm{.}3i+35\mathrm{.}00j+40\mathrm{.}0k\}N$ is still applied to the wrench at point $B.$ What is $M_x,$ the

moment of force at point O about the x axis?
