1. Mop - A mop (such as a floor mop) is a mass or bundle of coarse strings or yarn, etc., or a piece of cloth, sponge or other absorbent material, attached to a pole or stick. It is used to soak up liquid, for cleaning floors and other surfaces, to mop up dust, or for other cleaning purposes.
2. Doorknob- A standard doorknob lock set consists of a pair of knobs, one on each side of the door, that are connected through the door by a spindle and held together by mounting bolts. ... When either knob turns, it rotates the spindle, and the spindle retracts the latch and allows the door to open.
3. Screw - A screw is powered by the movement of the screw driver. It converts this rotational force (called torque) into up and down force. A screw's power depends on how close together the threads are and how far away from the center of the screw force is applied. You can get more power by making the threads closer together.
4. Stairs - Climbing stairs is a great way to amp your core muscle strength. Tones and sculpts your body: It also engages every major muscle in your lower body - glutes, hamstrings, quadriceps, abs and calves to exercise and thus tones your body better.
5. Nail- The physics of how nail works are simple. When driven into wood, the shaft of a nail pushes apart wood fibers as the point penetrates. The holding power of a nail derives from the simple friction of the displaced, bentwood fibers gripping the shaft of the nail.
6. Pulley - A pulley with one wheel allows you to reverse the direction of your lifting force by pulling down on a rope (that's looped over the wheel), lifting your weight. With a two-wheel pulley, you reduce the effort you exert to lift the same amount of weight. You lift the weight with half the force.
