1. The problem statement, all variables and given/known data You are holding a sign as shown below. The sign (including the horizontal bar it hangs from) has a mass of 1.80 kg and is 36.5 cm wide. The sign is hanging from a 1.30 m tall, 4.16 kg vertical post. The sign is symmetric with a uniform mass distribution as implied by the drawing. What external force (+ if up, - if down) and torque (+ for CCW, - for CW) do you have to apply with your hand to keep the sign in static equilibrium? [Use g = 9.80 m/s2 and ignore the width of the vertical post.] 2. Relevant equations Torque = Fd = 0 3. The attempt at a solution I'm not quite sure how to deal with the vertical stick. Torque = F1d1 - F2d2 - Fd3 = 0 As far as the set up goes, this is all I've got and I don't think it is correct. I may not be visualizing this problem correctly.
