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 is a Mechanical advantage equal to?
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
What is the formula used to calculate mechanical advantage?
Mechanical advantage=load/effort
Why is the actual mechanical advantage of an inclined plane alwaysess than the theoretical mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

What is the mechanical advantage of a wheel and axle?
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle.
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
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.
How do you make levers stronger?
They don't, they just give you a mechanical advantage.
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
What did Archimedes first use torque for?
Archimedes work on levers brought about the concept of torque. He used levers and pulleys to illustrate mechanical advantage. Torque and moments make us understand the mechanical concepts.
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.
Does a fixed pulley provide mechanical advantage?
yes
