Kamil is planning to make a profit by pulling his aching tooth with a "pulley"! 😂 But was there any gain in work or energy with simple machines? NEVER! We're covering the most mechanical topic of the 8th Grade Science "Simple Machines" unit – Pulleys, Gears, and Wheels – in a single video, without getting bogged down in formulas! In this lesson, we're deciphering the logic of the pulley, that legendary system once used to draw water from wells, but now found everywhere from door handles to steering wheels, faucet heads to screwdrivers. How can the force gain in a pulley be increased? Where are the force arm and the load arm? Then we move on to Gears and Pulleys, which transfer motion and power from the pedals of our bicycles to the inside of watches. We'll master the tactics of finding the direction of rotation and calculating the number of revolutions, essential for the LGS exam, in the most practical ways, in seconds. The secret of straight, cross, and concentric gears is in this lesson! 👇 VIDEO SECTIONS AND LESSON FLOW (Click Where You Want!) 👇 00:28 What is a Pulley?
