The screw is an inclined plane

Mark off and cut out a right angle triangle on a piece of white paper or a piece of wrapping paper. The triangle should be about 30 cm long on its base and about 15 cm long on its direct side. Secure a round rod about 20 cm long and roll the triangular piece of paper on the rod starting at the short side and rolling toward the point of the triangle.
