Question

A flagpole of length L = 2 m is attached to the wall at an angle θ = 60 ◦ from the vertical. The pole has a mass of M = 5 kg. There is a flag of mass m = 1 kg hung from the end. There is a horizontal wire that connects the end of the flagpole with the wall. (a) Draw a free body diagram of the system. Don’t forget to include the forces where the flagpole attaches to the wall. (b) Find the magnitude of the tension in the wire.
