Why is the mechanical advantage of second class levers is always greater than 1?
Wiki User

Because the load is always between the effort and the fulcrum,
so the effort arm is always longer than the load arm.

Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
What are the levers that operate at a mechanical advantage called?
functional 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.
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 makes the first class lever second class lever third class lever different?
1st order levers have the fulcrum between the load and effort arms. The mechanical advantage of these levers can be greater or less than 1, depending on the length of the arms.2nd order levers have the load portion between the effort portion and the fulcrum. These always have a mechanical advantage greater than 1. They increase the force exerted at the expense of distance.3rd order levers have the effort portion between the load portion and the fulcrum. These always have a mechanical advantage less than 1. They decrease the force exerted with a gain to the distance.
How do you make levers stronger?
They don't, they just give you a mechanical advantage.
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
What will increase the actual mechanical advantage of a machine?
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
What is the Mechanical Advantage of levers?
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.
What type of advantage describes the ability of a machine to incresae output force?
Mechanical Advantage [achieved through levers or pulleys]
How is mechanical advantage calculated for levers?
lenght of the effort arm divided by lenght of the load arm
What technologies have been used to invent the elevator?
wheel gears electricity levers mechanical advantage
