Question
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
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.
u = (-1/3)i+ (2/3)j+(2/3)k. He pulls with a force F = 36.0
lb from point A [(3.00, 4.00, 0.000) ft].
