A 2×12 board is about 2.18 kg per linear foot. A 16-foot length board of Southern Yellow Pine is placed against a wall such that the angle between the wall and the length of the board is 20°. Assume that the wall is perfectly smooth (a.k.a. the coefficient of friction between the wall and the board is zero). (a) What is the normal force between the wall and the board? (b) What is the normal force between the board and the floor? (c) What is the force of static friction between the board and the floor? (d) What is the coefficient of static friction between the board and the floor?
