question 27

Multiple Choice

-A light triangular plate OAB is in a horizontal plane.Three forces,F₁ = 2 N,F₂ = 4 N,and F₃ = 7 N,act on the plate,which is pivoted about a vertical axis through point O.In the figure,consider the counterclockwise sense as positive.The sum of the torques about the vertical axis through point O,acting on the plate due to forces F₁,F₂,and F₃,is closest to:

• A)2.2 N ∙ m
• B)2.6 N ∙ m
• C)-2.2 N ∙ m
• D)-2.6 N ∙ m
• E)zero
