A 150 pound man is standing on a lever one foot from the fulcrum. How much effort must be used to lift the man if the effort is applied six feet from the fulcrum?

6 x 150 pounds. 900 pounds of force would have to be applied.

What is the relationship between the load and effort that gives a lever system an adavantage?
the relationship between them is that the load carries it self and the lever holds its self in place
What are the wee hours in Cannes?
The wee hours in Cannes are referred to as 'lever du soleil' or 'lever de soleil' which means dawn or sunrise.

What type of a simple machine is a screwdriver?
Most say it is a lever, but i know for fact that it is actually considered a wheel and axle. - I'm in proving this and actually it is a lever because i was just taking a test that asked this question and it did not give me the option of a wheel and axle but it did give me lever. Edit~ The first person to answer was, in fact, correct. To the person who last improved the answer: Some people consider it a lever; it is actually a wheel and axle. A lever is a rigid object that rotates around a fixed point, like a seesaw, while a wheel and axle is two circular or cylindrical objects that are fastened together (The handle and the metal rod) and they rotate around a common axis (the screw)! :)
What is the part of a lever on which the effort force is applied is called?
Fulcrum
What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
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
What is a support called on a lever?
inclined plane
What is effort arm?
The portion between the fulcrum and the effort applied in a lever is called effort arm.
What is the fulcrum between effort and resistance?
a 1st class lever there are 3 types of levers, 1st 2nd and 3rd class. 1st: fulcrum between effort and resistance 2nd:resistance between fulcrum and effort 3rd: effort between fulcrum and resistance Fulcrum = a pivot point on a lever. Effort = force applied on lever Resistance = load 1st example:see-saw/scissors 2nd example:wheelbarrow/car door 3rd example:someone raking/ hockey stick being usued
Why is the elbow considered third class lever?
B. the effort is applied closer to the fulcrum than the load.
What are the parts a lever?

How does a first-class lever different from a second-class lever?
In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors. In second class lever fulcrum is at one end and effort is at other end. The load is at the middle. eg nutcracker.
How does a second-class lever differ from a first class lever?
In a first class lever the fulcrum is at the middle. load and effort are applied at two ends. eg scissors. In second class lever fulcrum is at one end and effort is at other end. The load is at the middle. eg nutcracker.
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.
