Levers have a greater mechanical efficiency that other simple machines because?
They have to overcome less friction
What is a major mechanical limitation of lever systems?
Levers are limited in how far the effort force or resistance can move. Other simple machines can overcome this limitation, such as the wheel and axle.
What are the simple machines in a human body?
Some simple machines include: your teeth- wedges arms- levers legs-levers finger nails- inclined planes elbow-lever knee-lever tendons- pulleys
What are examples of levers as simple machines?
seesaws are and example of levers,as one person goes up the other goes down in a simple lever position.
Is calculator a simple machine?
No. Simple machines are things like levers, inclinded planes.

Why do levers have a greater mechanical efficiency than simple machines?
The transmission lever is very simple and there is no friction.
What simple machines are in the body?
Levers. Mostly levers.
What are the levers that operate at a mechanical advantage called?
functional levers
Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
How do you increase the mechanical advantage of a wedge?
The spokes of a wheel are comparable to levers. Longer spokes give more mechanical advantage. Even in a wheel that is solid, and has no spokes, the greater the diameter, the greater the mechanical advantage.
Are levers simple machines?
Yes it is
What do levers have to do with mouse trap cars?
Levers are a big deal when it comes to Mouse Trap Cars, levers help make the mechanical advantage and ideal mechanical advantage higher and better.
What is a major mechanical limitation of lever systems?
Levers are limited in how far the effort force or resistance can move. Other simple machines can overcome this limitation, such as the wheel and axle.
How do simple machines change the force?
by levers
How are levers used?
Levers are useful because they transfer force over a distance. Levers are known for being simple machines and are easy to construct.
