A box sits on a horizontal wooden board. The coefficient of static friction between the box and the board is 0.5. You grab one end of the board and lift it up, keeping the other end of the board on the ground. What is the angle between the board and the horizontal direction when the box begins to slide down the board?

The critical angle is determined by the condition: Coefficient of static friction is equal to the tangent of angle between tangent and applied force..

From this equation we can find an angle .
