How would you use the word advantage in a sentence?
he was at a greater advantage as he did not skip his previous class unlike his friend
How do the three classes of levers work?
Class 1: Fulcrum in the middle: the effort is applied on one side of the fulcrum and the resistance on the other side, for example, a crowbar or a pair of scissors.Class 2: Resistance in the middle: the effort is applied on one side of the resistance and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, a bottle opener or the brake pedal of a car. Mechanical advantage is greater than 1.Class 3: Effort in the middle: the resistance is on one side of the effort and the fulcrum is located on the other side, for example, a pair of tweezers or the human mandible. Mechanical advantage is less than 1.

What are the 3 classes of levers?
Levers are classified into three types (first-class, second-class, and third-class) depending on the relative position of the fulcrum (pivot point), the point of applied (input) force, and the location of the load (output force). In a first-class lever, the fulcrum is between the input force and the output force, and the load is moved in the opposite direction of the applied force. Placing the fulcrum closer to the load gives an advantage of force (less force needed to move the load a shorter distance), while a fulcrum closer to the point of applied force gives an advantage of distance (the load is moved a greater distance but more applied force is needed). First-class levers include a crowbar, using a hammer's claw end to remove a nail, and a pair of scissors. In a second-class lever, the load is between the fulcrum and the point of applied force, so both forces move in the same direction. Less force is needed to move the load, but the load does not move as far as the direction over which the input force must be applied. Examples include the wheelbarrow, a bottle opener, and a door on its hinges. In a third-class lever, the input force is applied between the fulcrum and the load, and both move in the same direction. The amount of applied force is always greater than the output force of the load, but the load is moved a greater distance than that over which the input force is applied. Examples include a hammer driving a nail and the forearm of a person swinging a baseball bat.

Why are third class levers used if their mechanical advantage is less that one?
Mechanical advantage is not the only reason to use levers.
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
Which statement is true about the ideal mechanical advantage of a third-class lever?
mechanical advantage is the output force divided by the input force
What is the mechanical advantage formula for a 1st class lever?
fd=MA
Which type of lever always increases mechanical advantage?
second class lever
Mechanical advantage of a 3rd class lever?
always less than 1
The mechanical advantage of a second class lever?
... is always less than 1 .
The mechanical advantage of a second class lever is?
idk go ask your teacher
How do you change the mechanical advantage of first class lever?
Move the focal point of the leaver.
What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
Is an oar a first class lever?
Yes, but its Mechanical advantage is usually less than 1
