Question 11
11) A 45 kg. girl is sitting on a seesaw 0.6 m from the balance point. How far, on the other side, should a 60 kg. boy sit so that the seesaw will remain in balance? = 45 kg =0.6m = 60 kg 12) A solid cylinder consisting of an outer radius R₁ and an inner radius R₂ is pivoted on a frictionless axle as shown. A string is wound around the outer radius and is pulled to the right with a force F₁ = 3N. A second string is wound around the inner radius and is oulled down with a force F₂ = 5N. If R₁ = 0.75 m and R₂ = 0.35m, what is the net torque acting on the cylinder? F₁
