1. The problem statement, all variables and given/known data a large stone obelisk that is 8meters tall is laid down flat in the center of a Roman piazza and is going to be tilted into place by a rope and pulley system tied to a team of donkeys. If the team of donkeys always pulls with a constant force of 4500N, what is the torque if: a) the rope is attached to the middle of the obelisk b) the rope is attached to the end of the obelisk at a 45 degree angle? c) the rope is attached perpendicularly to the end of the obelisk? 2. Relevant equations t = F * I 3. The attempt at a solution a) 4m * 4500 = 18,000N*m b) (8m)(cos45)(4500N) = 25455N*m c) is it zero?
