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]. > View Available Hint(s) M2, M, M, = 306,-241,394 N.m Submit Previous Answers v Correct Term 1: Correct answer is shown. Your answer 306.13 N ·m was either rounded differently or used a different number of significant figures than required for this part. Term Correct answer is shown. Your answer -240.53 N m was either rounded differently or used a different number of significant figures than required for this part Term 3: Correct answer is shown. Your answer 393.59 N. m was either rounded differently or used a different number of significant figures than required for this part. 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.
