Naz Mariwan Science Coursework Mr Millington
Levers Coursework
For this Piece of coursework I will be investigating a report on the use of mechanical machines in the workplace. Most machines have one main thing in common; this is that they are used to move things for example screwdrivers; however there are many more, much more complicated things like bikes. Most machines are made up of a number of small simple machines such as levers, pulleys and gears. As machines are used mainly to move things, an effort is needed to move a load from one place to another.
Gears
A simple gear is chain is a series of interloging cogs with different diameters. When one cog turns, it makes another turn however it turns in the opposite direction and the cogs are fixed to shafts. The mechanical advantage of a machine tells you how big the load is compared to the effort or how much difference a machine makes to the force.
