Artwork: How pulleys work#2: With two wheels, it's as though the weight is hanging from two ropes (the two strands of the same rope on the left), and a pulley halves the lifting force you need. It's like lifting the weight with two ropes instead of one. But you now have to pul...
How Does A Pulley Work? Pulleys are simple machines with one or more wheels over which a rope is looped. Pulleys can help us lift heavy things more easily. Our homemade pulley system below doesn’t necessarily reduce the weight of our lifting, but it does help us move it with less effo...
If you want to transport objects to a higher height or want to test out physics, build an elevator pulley. Pulleys are simple wheels with grooved rims that are pulled by a rope. Pulleys are useful for elevators because they lift more than their weight. The longer the string length, the m...
The more work you have to do to draw a bow, the more energy it can transfer to an arrow. Compound bows usepulleysto help people do more work on the bow with less physical effort. In addition, when fully drawn, a compound bow's pulleys often hold part or even most of the draw weig...
When you have more pulleys, does the mechanical advantage and efficiency increase or decrease? What is a moving coil galvanometer ? Explain in detail. Explain the difference between energy and power. How they are related to work? Explain briefly, how mutual inductance works and why it ...

We even picked up a few different pulleys at the hardware store and have been testing them out with different items. My son has loved our super-simple indoor LEGO zip line, but it is time to take the engineering outdoors! Plus it’s the perfect activity to add to our 31 Days of Out...
So, [the activity] was a STEM production in creating toys with pulleys and gears and incorporating into that. So, the main theme was good—a theatre, little miniature theatre or puppet show and with the physics of mechanics and pulleys. I remember someone very creative using all her makeup...
How do you relate acceleration in two systems connected by pulleys? Why is the direction of magnetic dipole moment from south to north pole? Show on a diagram of how your CM shifts when you change from a lying position to a sitting position. ...
pulleys and flywheels that had previously distributed power, all of which could trap arms, clothing and hair. No flywheel also meant that a machine could stop immediately rather than taking time to spin down. And electricity allowed the factory to be completely reorganized: no longer confined to...
