Tweedledum and Tweedledee are carrying a uniform wooden board that is LLL = 3.00 mm long and has a weight of w = 160 N. Tweedledum applies an upward force of magnitude F1 = 60.0 NN at the left end of the board.

Which of the following is the correct equation for Στ for the given rotation axis? All rotation axes lie on the x-axis and torques that would cause a counterclockwise rotation are positive.

Enter the letter(s) of the correct equation(s) in alphabetical order. For instance, if you thought that choices A, B, and D were correct, you would enter ABD.

Answer Choices:

	Axis of Rotation	Et
A	x=0	(1/2)wL+F₂d=0
B	x=L	(1/2)wL-F₂(L-d)-F₁L=0
C	x=0	(-1/2)wL+F₂d=0
D	x=d	-F₁d-F₂(d-(1/2)L)=0
E	x=(1/2)L	(-1/2)F₁L+F₂(d-(1/2)L)
F	x=(1/2)L	(1/2)F₁L+F₂(d-(1/2)L)
