What. Are the parts of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
Do the fulcrum is part of the bar which moves or carries the load?
The fulcrum is the part that the bar sits on to form a lever. The output arm is the part that the load sits on.
What the solid bar that rests on a fulcrum?
The lever? There are probably other names for it, but i was always taught the fulcrum, lever, and load. Load closer to fulcrum, easier to lift load. (longer lever= mechanical advantage) This would fall under simple machines in science class.
What effect does moving the fulcrum have on a lever?
Moving the fulcrum on a lever will effect it by making it easier or harder to move the load. A lever is defined as a simple machine that consists of the fulcrum and a rigid bar.
Is a bar on a fulcrum a pulley?
yes,a fulcrum needs a bar to lift an object but a pulley does not need a bar

What are parts are of a lever?

Do the fulcrum is part of the bar which moves or carries the load?
The fulcrum is the part that the bar sits on to form a lever. The output arm is the part that the load sits on.
What are examples of lever and fulcrum?
An example of a lever is a crow bar. The fulcrum would be where the bar touches the ground, that is what the bar is rotating around.

What force is necessary to lift a rock weighing 150 kg by using a bar that is 2.0 meters long if the fulcrum is placed 30 cm from the point where the bar contacts the rock?
Total length of the lever = 2 meters = 200 cmLength of load arm (fulcrum to rock) = 30 cmLength of effort arm (fulcrum to effort-point) = 200 - 30 = 170 cmMechanical advantage = effort arm/load arm = 170/30Weight of the rock = Mass x gravity = 150 x 9.8 = 1,470 newtonsEffort = weight/M.A. = 1,470 x 30/170 = 259.4 newtons.(That's the apparent weight of 26.47 kg of mass.)
Is a bar on a fulcrum a pulley?
yes,a fulcrum needs a bar to lift an object but a pulley does not need a bar
Why is a rigid bar that rests on a fixed point called a fulcrum?
The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?
Are levers 1st class or 2nd or 3rd?
Levers can be all of them. A first class lever is when the pivot (funcrum) is in the middle. A second class lever has the load (resistance) in the middle, and the third class lever has the effort (force) in the middle. For example, a see-saw is a first class lever because the fulcrum is the in middle. A exmaple for a second class lever would be a can opener because the load, the can, is in the middle. And last, the thrid class lever is a arm because the effort is in the middle, because your elbow gives the effort to move the arm.
What do fixed fixed pulleys always do?
A fixed pulley when used individually, uses more effort than the load to lift the load from the ground. This is what a fixed pulley always does. When attached to an unmovable object e.g. a ceiling or wall, it always acts as a first class lever where the fulcrum is located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push it up and down. The disadvantage is that you have to apply more effort than the load.
