Learning Goal:
To understand the concept of moment of a force and how to
calculate it using a scalar formulation.
MR, = -4.54 N·m
The magnitude of the moment of a force with a magnitude F
around a point O is defined as follows:
Submit
Previous Answers
Мо — Fd
where d is the force's moment arm. The moment arm is the
v Correct
perpendicular distance from the axis at point O to the force's
line of action.
Part C
As shown, a server at a restaurant is carrying a tray that has a glass of water resting on it. (Figure 3) The glass and tray exert a force with
magnitude Fi = 28.5 N on the server's hand. If l1 = 0.390 m , l2 = 0.290 m , l3 = 0.130 m, ai = 155 °, and 2 = 120 °, what is the moment of
force about the shoulder joint at point A? Assume that moments acting in the counterclockwise direction about point A are positive whereas
moments acting in the clockwise direction are negative.
