    It’s said that necessity is the mother of invention. Calvin said that his mother is necessary for this invention.

    Lever, inclined plane, wedge, screw, wheel-and-axle, and pulley-and-line. I see the inclined plane as inherent in the wedge (inclined plane moved used to split) and the screw (wraped in a helix), while the wheel and pulley are similar to the lever.

    Also, why is the hammer not included? Is it too hard to figure out the mechanical advantage of converting kinetic energy into force?
