Find the force in member BD.A 40 lb ladder 12 ft long leans against the wall making an angle of 30° with the wall. When a 180 lb man reached a point 8 ft from the lower end, the ladder is about to slip. Calculate the coefficient of friction between the ladder and the floor. The coefficient of friction between the ladder and the wall is 0.20
