Levers belong to a class of devices known as simple machines, which also includes gears, pulleys, inclined planes, wedges and screws. (The word "machine" itself comes from a Greek word that means "help make easier.") All simple machines share one trait: They multiply...
Determine the pulley ratio. The pulley ratio depends on the size of the two pulleys. Since the drive pulley is 2 inches and the driven pulley is 4 inches, the pulley ratio is 4 divided by 2, which equals 2. This means that the drive pulley has to turn two times to turn the driven ...

There are two major types of rear derailleurs: high normal and low normal styles. High normal derailleurs automatically return to the smallest sprocket when the shifting cable tension is released. What does a rear derailleur do? The rear derailleur shifts the chain at the rear sprockets to chan...
How To Convert Bifold Doors To Barn Doors 1 | Measure and calculate Before you start, make sure you have enough space beside your doorway for the door to slide all the way over. Since my doors are 2 feet wide, I needed 2 feet on either side of the door in order to be able to op...
To calculate the equivalent resistance divide the battery’s full charge voltage by the current draw you measured above the result is the number of ohms of resistance you need to simulate your motors. Make sure the resistor you use can handle the load otherwise it will overheat and burn up....
that means it will take 3200 steps in order the motor to make full 360 degrees movement. Now depending on the transmission type, or in this case the size of the pulleys, we need to calculate the number of steps the motor needs so the machine moves 1mm. The default value here is set ...
Cassette drive belts usually become stretched and hard and sometimes turn into a gooey tar-like mess, making it very difficult to determine their size. I usually use the "string method" which involves using a piece of string to thread around the pulleys the belt path would take. The length...
dirt from belts and pulleys. Remove chips to avoid damage to moving parts. Wipe all spindles and sleeves free of grit to avoid damaging the precision fit. Put a light coat of oil on all unpainted surfaces to prevent rust. Operate all machines with care to avoid overworking the electric ...
