PPT-Pulleys

The Big Idea of this Investigation A simple machine is a mechanical device that makes work easier by magnifying modifying transferring or changing the direction of applied force Simple machines are the elementary building blocks of which all complicated machines are made. Designed for direct application to the drive pulley this product can transform any belt system into a highperformance lowmaintenance operation In addition to providing outstanding increases in the coefficient of friction traction between the belt an Designed for direct application to the drive pulley this product can transform any belt system into a highperformance lowmaintenance operation In addition to providing outstanding increases in the coefficient of friction traction between the belt an and.

Coupled Motion. Coupled motion problems are problems in which the movement of one object directly impacts the motion of another object.. We have already briefly covered this topic when talking about pulleys.. Ignition and compression within an engine results in acceleration and deceleration of the crankshaft. These rotational variances are then transferred to the engine 1. Lecture. 21. Using. . Machines. Ozgur. . Unal. Machines. A . machine. . is a device . that. . makes. . doing. . work. . easier. ..

(This means you don’t have to write this!!). Building a house. Lifting a car. Building the pyramids. Review Newton’s Second Law. Pulley on horizontal surface. Given a mass of 14 kg on a horizontal table. It is attached by a rope over a pulley to a mass of 26 kg which hangs vertically. . μ. = 0.1. What is a pulley?. A pulley is a wheel. A pulley uses rope that goes around the pulley in its groove. The rope attaches to objects. Force is applied to the . other. end of the rope . Why use a pulley wheel and not just rope looped around the beam?. What is a Pulley?. Is a wheel with a grooved rim in which a rope can run to change the direction of the pull (force) that lifts the load.. How to Build Your Pulley. Use the following steps:. Clip a binder clip to the end of a half-meter stick.. Jiwi’s science extras clip for EPISODE 2 shows pulleys being used to lower the sh tank to the table as the door is opened. This is a demonstration that pulleys are used to change the dir
