Chapter 6, Problem 16PQ
A filled treasure chest of mass m with a long rope tied around its center lies in the middle of a room. Dirk wishes to drag the chest, but there is friction between the chest and the floor with a coefficient of static friction μs. If the angle between the rope and the floor is θ, what is the magnitude of the tension required to just get the chest moving? Express your answer in terms of m, μs, θ, and g.
