What happens when you increase the length of lever?
When you increase the length of a lever, you increase the mechanical advantage of the lever. This means that you can exert less force to move the same load. Additionally, increasing the length of the lever can also increase the distance over which the force is applied, allowing for larger movements with less effort.
Which of the following would increase the output force of a lever?
Increasing the length of the lever arm or applying a larger input force would increase the output force of a lever.
How do you find MA in lever?
To find the mechanical advantage (MA) of a lever, you can calculate it by dividing the length of the effort arm by the length of the load arm. The formula is MA = Le / Ll, where Le is the length of the effort arm and Ll is the length of the load arm.
In which class lever MA greater than one?
A class 2 lever can have a mechanical advantage (MA) greater than one. In this type of lever, the load is situated between the fulcrum and the effort, allowing for an increased output force compared to the input force applied.
What type of lever does not increase force but does increase the speed or distance a load travels?
A third-class lever does not increase force but does increase the speed or distance a load travels. In a third-class lever, the effort is between the load and the fulcrum, which results in the load moving a greater distance or speed when the effort is applied.
How do you increase the MA of a 1st class lever?
Move the fulcrum farther from the force and closer to the load.
MA of a first class lever?
Class-III Lever . . . MA always less than 1. Class-II Lever. . . . MA always more than 1. Class-I Lever . . . . MA can be 1, more than 1, or less than 1.
What is the formula for MA of a lever?
The mechanical advantage (MA) of a lever is calculated using the formula: MA = Length of effort arm / Length of resistance arm. The effort arm is the distance from the fulcrum to where the effort is applied, while the resistance arm is the distance from the fulcrum to the load being moved. This ratio indicates how much the lever amplifies the input force. A higher MA means the lever provides greater force amplification.

How do you make the MA of a lever better?
Move the fulcrum closer to the load.
In which class lever MA greater than one?
A class 2 lever can have a mechanical advantage (MA) greater than one. In this type of lever, the load is situated between the fulcrum and the effort, allowing for an increased output force compared to the input force applied.

A third-class lever does not increase force but does increase the speed or distance a load travels. In a third-class lever, the effort is between the load and the fulcrum, which results in the load moving a greater distance or speed when the effort is applied.
What is the MA of a 1st class lever that is 24 cm long and the fulcrum is 0.5 cm from the resistance?
The ideal MA is 47.
A lever has 36cm input arm and 6cm output arm. What is the MA?
The mechanical advantage (MA) of a lever is calculated by dividing the input arm length by the output arm length. In this case, the MA would be 36cm (input arm) divided by 6cm (output arm), resulting in a MA of 6.
What is the MA of a lever if the resistance arm is 20cm and the effort arm is 100cm?
The mechanical advantage of a lever is calculated by dividing the length of the effort arm by the length of the resistance arm. In this case, the MA would be 5 (100cm/20cm).
