Your mission is to find an equilibrium state. To achieve your goal, you
can modify three parameters: the coefficient of friction, the shape of
the block and the the angle theta.
HOW TO PLAY:
Enter a value for the coefficient of friction.
Enter a value for h/b by typing a value or moving the scrollbar.
Enter a value for theta by typing a value or moving the scrollbar.
Click on the GO Button to see the behaviour of the block.
