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 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.
How do you increase the mechanical advantage of third class lever?
To increase the mechanical advantage of a third-class lever, you can adjust the distances between the effort force, the fulcrum, and the load. By increasing the length of the effort arm or decreasing the length of the load arm, you can increase the mechanical advantage.
What class or classes of lever always have a mechanical advantage greater than 1?
Class 1 and Class 2 levers always have a mechanical advantage greater than 1. In a Class 1 lever, the input arm is longer than the output arm, while in a Class 2 lever, the output arm is longer than the input arm, resulting in a mechanical advantage greater than 1.
What is the mechanical advantage of a first-class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?
answer is 4
Why cant a third class lever have a mechanical advantage of 1 or more?
A third class lever has the effort force between the fulcrum and the load, which results in a mechanical advantage of less than 1. This means that the input force needed to lift the load is greater than the load itself, making it mechanically disadvantageous for lifting heavy objects.
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
Which if the following machines always has a mechanical advantage of less than 1?
A machine with a mechanical advantage of less than 1 is always a Class 3 lever. In a Class 3 lever, the effort force is applied between the fulcrum and the resistance force, resulting in a mechanical advantage always less than 1.
Which type of lever always increases mechanical advantage?
second class lever
Which tyoe of lever always increases mechanical advantage?
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
What would increase the mechanical advantage of a second class lever?
Increasing the distance between the pivot point and the effort force, or decreasing the distance between the pivot point and the load, could increase the mechanical advantage of a second-class lever. Additionally, using a longer lever arm can also increase the mechanical advantage.
What is the relationship between distance from the fulcrum and the mechanical advantage of a first class lever?
In a first class lever, as the distance from the fulcrum to the point where the input force is applied increases, the mechanical advantage also increases. This means that the lever becomes more efficient at moving a load with less effort.
