Question

Part A Learning Goal: To understand the concept of moment of a force and how to calculate it using a vector formulation. 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. man wishes to spin a merry-go-round in the x-y plane centered 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 direction of the unit vector u = (-1/3)i+(2/3)j + (2/3)k. He pulls with a force F 35.0 lb from point A [(3.00, 4.00, 0.000) ft]. t the View Available Hint(s) force in the Πνα ΑΣφ vec M M M 340 lb ft Figure 1 of 1 Your submission doesn't have the correct number of answers.
