Homework Statement
Michael is trying to raise a barrel using sections of pipe.The three objects are horizontal cylinders resting on level ground. The barrel has a mass of 100 kg and its diameter is 2.0m. Each pipe has a diameter of 0.50 m. What minimum horizontal force must his feet exert on the pipe to raise barrel from the ground? Neglect Friction.
Homework Equations
Newton's first law, newton's second law, newton's third law...
The Attempt at a Solution
well, i figure that the pipe in the corner against the wall has no acceleration, but because of newton's third law exerts a force equal to force applied onto the barrel (force contact). now, im just confused after where to go now.
i thought about it, and the distance between the two cylinders, pipe and barrel, must 1.5m.
thats as far as i got. PLEASE HELP! D:
