Why does a class 3 lever does not have the same mechanical advantage of a class 2 and 1 lever?

because they are smaller than the level 3 that's why

Why does a class 2 lever will always have a greater mechanical advantage than a class 3 lever?
Mechanical Advantage is given by the following equation: MA = Load Effort On a class 2 lever, the fulcrum (pivot) is at one end of the lever and the work applied is at the other end. The load is then applied near the fulcrum, as common with the wheel barrow. A class 3 lever has the effort applied between the fulcrum and the resistance. Therefore, a much greater effort will be required to produce the same moment value. A typical C2 lever has a much greater distance in which to produce the load than a C3 lever.
What effort force would be needed to lift a load of 150 N with a lever system that has a mechanical advantage of 3.5?
Well lets see. I suppose that a ballance is a lever advantage of one: which of course is the same on both sides; that is no advantage. So a lever of an advantage of two, is, half of that same force on the other side. So the answer is (half of 150) or 75N.
How are second class levers and third class levers similar?
Depending on condition of course. 3 boxes and taken care of $2200 easy. Dont let anyone tell you differently. These guns are extremely rare and people will tell you they are far less with the intent of making people think that are not as valuable as they are. As time goes on of course, they become more and more valuable. These were "working" guns for those serious about accuracy etc... Because of this very few of them are in excellent condition.
What kind of lever is a seesaw?
yes it is a 1st class lever and so is a pair of pliers!!!!
Can a pulley system provide both a directional advantage and mechanical advantage at the same time?
yes
How is machanical advantage calculated for a third class lever?
Mechanical advantage: Class-I lever . . . can be any positive number Class-II lever . . . always less than ' 1 ' (and more than zero) Class-III lever . . . always more than ' 1 '

Is force the same thing as mechanical advantage?
No. You'll never see a bathroom scale that says your mechanical advantage is 140 pounds. The mechanical advantage of a device like a lever or a hydraulic jack is a measure of how the force changes between the input of the device and its output.

The mechanical advantage of a machine is the number of times it?
The mechanical advantage of a machine is the number of times it can perform the same task without breaking down.
Can a pulley system provide both a directional advantage and mechanical advantage at the same time?
yes
When you are solving for mechanical advantage what units did the final answer require?
None. Mechanical advantage is a ratio of two measures each of which has the same units and so it is a unit-less number.
Does mechanical advantage have the units of force?
No, mechanical advantage has no units, it is simple the ratio of an output quantity, such as force, to the input quantity. For example if it takes 10 pounds to lift a 50 pound object, the mechanical advantage is = 5
Does a third class lever increase the distance a load can be moved?
Levers can turn a small applied force into a large force. The same amount of work is done, though. So the small force must be applied over a larger distance, and the large force acts for a small distance. I think for the second way: you can configure a lever to operate in the same direction as the applied force, or in the opposite direction, depending on where the pivot point is. So it can change the direction of the force.
What is the mechanical advantage of a machine that changes only the direction of applied force?
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
