Just need part B solve carefully! Thank you ! Use image below
+ Moment of a Force: Vector Formulation
Learning Goal:
What are the x, y, and z components of the resulting moment acting on the merry-go-round about the origin?
To understand the concept of moment of a force and how
to calculate it using a vector formulation.
Express your answers numerically in Newton-meters to three significant figures separated by commas.
A man wishes to spin a merry-go-round in the x-y plane
centered at the origin (0.000, 0.000, 0.000) . (Figure 1)
Because he must pull upward and cannot stand on the
merry-go-round, he must apply a force in the direction of
the unit vector u = (-1/3)i+ (2/3)j + (2/3)k . He
pulls with a force F = 328 N from point A
[(1.10, 1.40, 0.000) m].

Because a merry-go-round is free to rotate about the z axis, a moment about the x or y axis is easily overlooked. Just because a body is not free to rotate in a direction do
mean that a moment's component does not exist in that direction. For example, a moment about the x or y axis on a poorly designed merry-go-round can cause the merry
round to wobble up and down.
