Compound
Machines |
|
|
|
Introduction:
| All machines make the
work easier. Without using machines many tasks are virtually
impossible. Although simple machines are used as useful tools,
most machines are a combination of two or more simple machines.
Such machines are called compound machines.
Compound machines help us to cut
and form material, lift heavy objects, transport heavy objects or
more complex tasks such as packaging, sewing, mixing and many
more. |
 |
In this project you will construct a compound
machine using two or more simple machines.

Material and instructions:
In this project you will use
wood, nylon string, pulleys and some other material to make models of a
winch, a power lift, an elevator or other similar machines that are used
to lift heavy objects. More advanced students may also calculate the
mechanical advantage of their machine and report it in the form of a
table, a graph or both. |
