A uniform board is leaning against a smooth vertical wall. Theboard is at an angle above the horizontal ground. Thecoefficient of static friction between the ground and the lower endof the board is 0.550. Find the smallest value for the angle, such that the lower end of the boarddoes not slide along the ground.
