Suppose you have a stack of 17 identical steel bars (steel bars have a mass of 1.00kg each). You are required to pull out bar number 16 from the stack (counting from the top of the stack down). Assuming that your assistant holds all other bars in place.   If the coefficient of friction between steel and steel is 0.750, how hard do you have to pull (in N)?

A 10.0 kg mass is at rest on a board inclined at an angle of 30.0o above the horizontal. The mass is held in place by the combination of static friction and the 10.6 N tension in a cord attached to the mass on the uphill side, and running parallel to the board. Find the coefficient of static friction (s) between the mass and the board.
