Why are levers often included in the design of objects for people who can't use their hands easily?

Levers allow you to manipulate heavy things with less force, at the cost of more distance traveled.

The future for static and dynamic engineering systems?
Statics deals with stationary objects(bridge). Dynamics deals with things in motion(cannonball). A Civil Engineer deals with statics a lot more. They design buildings, bridges, roads, ect.. to NOT MOVE. In fact, in Civil Engineering if something moves it is Failure! That is how failure is defined.. movement. A Mechanical Engineer deals with dynamics a lot more. They design machines, mechanisims, and things with moving parts. Like levers, pulleys, etc. They WANT things to move and design them accordingly. The study of Statics (objects at rest) and Dynamics (objects in motion) is the basis for much of engineering. Along with a class called strength of materials, which deals with the mechanics of the materials used in the machine, building, etc.
Classification of levers?
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
What simple machines are in the body?
Levers. Mostly levers.
How are levers classified?
levers are classified by the locations of the input and output forces relatively to the fulcrum
What are the advantages and disadvantages of levers?
Levers will wear and tear after use and money will have to be spent to repair or replace them.
What are levers used for?
levers are used to lift up objects
How do you lift heavy objects efficiently?
By using the principle of levers.
What objects work on the principle of moments?
-- levers -- wrenches -- stop-watches
Is a claw hammer a lever?
Yep! I am not sure what class but it is! Levers help lift heavy objects. Levers work by the farther you are from the fulcrum or pivot as compared to the heavy objects, the lesser the force you will need to lift or pull the object.
Which bones help the body move for lifting objects?
Just about every bone in teh body helps move or lift objects. bones act as levers for the muscles to contract against. wiki on!
What are the differences between levers and linkages?
A lever is something that moves around a central fulcrum A linkage is something that connects two objects
What does simple machines change?
Simple machines such as pulleys, wedges, and levers reduce the amount of energy required to lift or move (heavy) objects.
How were levers used in ancient times?
Yes, The Shaduf was used. A Shaduf is what the Egyptians used to collect water.
Is their a lever on a bike?
Yes. A bike will have several levers. The crank arms are levers, the brake levers are levers, the shifters are levers, the handle bar is a lever.
Do cars have levers?
yes They do have levers
