Move the fulcrum point so it is more than halfway toward the object being moved.

What would increase the mechanical advantage of a first class lever?
Move the fulcrum (pivot) farther from the effort and closer to the load.
What lever would have more mechanical advantage than one with a resistance are of 3 inches and an effort arm of 6 inches?
increase the effort arm to 8 feet
How you would measure the mechanical advantage of a bicycle?
Describe how you would measure the mechanical advantage of a bicycle.
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.
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.
Would motorcycle brakes be concidered a lever?
Leverage (mechanical advantage) will be found on all braking systems.

What is the mechanical advantage of a movable pully?
for one movable pulley you would get a mechanical advantage of 2

How does a decrease in height affect the actual echanical advantage of the inclined plane?
Since the Mechanical Advantage of the inclined plane is inversely proportional to its height, increasing the height would lower your mechanical advantage and lowering the height would increase it.Alternately, mechanical advantage is directlyproportional to an inclined plane's length, therefore increasing the length would increase your mechanical advantage.
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 for a 2-meter-long lever has an effort arm lenght of 1.6 meters?
4Explanationfor a lever,effort * effort arm = load *load armso by re arranging above equation,load/effort = effort arm/load armNow, as load/effort is called mechanical advantage so,mechanical advantage = effort arm/load armAs total length of rod is 2 m out of which 1.6 m is effort arm so remaining 0.4 m would be load arm. thus on putting values in the above equation, we getmechanical advantage = 1.6/0.4 = 4
What is meant by the term mechanical advantage?
A lever is a very useful tool that lets us exchange weight for distance. For example (theoretically) if you had to move a 200 pound sack into a car, but couldn't lift it, you could divide it into 8 parts, each being 25 pounds, and move each one individually into the car. It would be easy, however it would take more distance (lifting into the car 8 times instead of 1)
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
