A band brake consists of a lever attached to one end of the band. The other end of the band is fixed to the ground. The wheel has a radius of $$200$$ $$mm$$ and the wrap angle of the band is $${270^ \circ }$$. The braking force applied to the lever is limited to $$100N,$$ and the coefficient of friction between the band and the wheel is $$0.5.$$ No other information is given.
