1 The uniform dresser has a weight of 85 lb and rests on a tile floor for which μs = 0.28. If the man pushes on it in the direction θ = 30°, determine the smallest magnitude of force F needed to move the dresser.

2 The uniform dresser has a weight of 93 lb and rests on a tile floor for which μs = 0.26. If the man has a weight of 150 lb and pushes on it in the direction θ = 30°, determine the smallest coefficient of static friction between his shoes and the floor so that he does not slip.
