Learning Goal: To understand the concept of moment of a force and how to calculate it using a vector formulation. Part A 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 = 30.0 lb from point A [(3.00, 4.00, 0.000) ft). What are the x, y, and z components of the resulting moment acting on the merry-go-round about the origin? Express your answers numerically in pound-feet to three significant figures separated by commas. M2, My, M; = 80, -60, 20 lb - ft Previous Answers Completed Part B Find M, the magnitude of the moment, and 0, the angle between r and the force F. Express your answers in pound-feet and degrees to three significant figures separated by a comma. Figure < 1 of 1 να ΑΣΦ vec M,0 = Ib - ft,degrees Submit Request Answer Provide Feedback Next >
