Levers and pulleys are uncomplicated machines that make work easier by improving mechanical advantage, meaning that they reduce the effort needed to do a task. They provide "leverage," changing the direction of our effort.

Following are the different types of pulleys: #1 Fixed pulley #2 Movable pulley #3 Compound pulley #4 Block and tackle pulley #5 Step pulley

“A movable pulley is one whos block is movable. One end of the cord is fastened to the beam, and the weight is sspended from the pulley, the other end of the cord being drawn by the application of a force P. A little consideration will show that if P moves through a certain distance, say 1 foot, W will move through half that distance, or 6 inches; hence, a pull of 1 pound at P will life 2 pounds at W.” — Hallock, 1905

Here we have a 3:1 mechanical advantage. First one end of the rope is attached directly to the load, this is then passed around an…

We went to a local manufacturing museum recently. The boys loved it. One of the hands-on exhibits had them pulling weights attached to a pulley to simulate horsepower. They roamed the museum but kept coming back to pull those ropes. That moment precipitated this one. We made our own pulley with supplies we had at home. Supplies paper punch empty ribbon spool empty, clean small plastic bowl (e.g. empty fruit cup, etc.) yarn pencil or small wooden dowel rod tape (optional) small objects to put…

Exploring Gears with PASTA! I dyed some pasta one night to use for some crafts. One of the kinds I had was mini wagon wheels, and when I brought them inside from drying in the garage overnight, my brain was chanting "gears!" so I grabbed some toothpicks and cardboard boxes and made a wagon wheel gear train. I had to share it with the kids (and you too)! Materials needed for gear pasta: wagon wheel pasta (dye if desired) toothpicks cardboard box Get started on this gear STEM activity Pick out…
