Want this question answered?
Yes.
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
Because of the lever's mechanical advantage.
2nd class
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
Yes.

The third class lever functions between the input force and the output force

First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.
first class lever. Why? because it is in the order of output force-fulcrum-input force. output force ______________________________ input force fulcrum
2nd class
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
hhhhh
Just divide the output force by the input force.Just divide the output force by the input force.Just divide the output force by the input force.Just divide the output force by the input force.
In a closed system in the "real world" in which we live, there are losses associated with friction and other actions. These forces "take energy" from the system between its input and output. When we apply force to the imput of a system, some is lost as the force is transferred through that system. That means that the output force we observe will always be a bit less than the input force. A transmission in a vehicle is a classic example of the idea that there are losses between the input and the output of a system. The input from the engine will always be a bit greater than the output at the tailshaft (or axles for a transaxle) due to losses within the transmission.
