How does the position of the fulcrum change the nechanical advantage?
You get greater mechanical advantage the closer the fulcrum is to the resistance (load).

answer is 4
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 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.
When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage

What is a mechanism of a lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
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 is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
What is the Ideal Mechanical Advantage of a lever that has a fulcrum in the exact center?
One.
How do you increase the mechanical advantage of a lever?
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
How do you calculate the mechanical advantage of a first class lever?
It's the ratio of the distances effort-fulcrum/load-fulcrum.
