What is the mechanical advantage of a lever with an input arm of 5 m and an output arm of .5?
3
What is the mechanical advantage of a lever that has an input arm of 3 meters and an output arm of 2 meters?
The mechanical advantage of a lever is calculated by dividing the length of the input arm by the length of the output arm. In this case, the mechanical advantage would be 3/2, which simplifies to 1.5. This means that for every 1 unit of effort applied to the input arm, the lever can lift 1.5 units on the output arm.
Type of lever where fulcrum is found on the end?
A Type 3 lever has the fulcrum on one end, the input force on the other end, and the output force in the middle.
What are the components of the lever?
The components of a lever include a rigid bar, also known as the lever arm, a pivot point called the fulcrum, and the input and output forces. The input force is the force applied to the lever to produce motion, while the output force is the force generated at the opposite end of the lever.
A mover wants to use his own weight to lift a 450-pound box with a lever and a fulcrum He weighs 150 pounds If the output arm is 1 meter long how long does the input arm need to be?
3 meters
In what class of a lever is the effort between the fulcrum and the resistance?
In a class 1 lever, the fulcrum is located between the effort (input force) and the resistance (output force). Examples of class 1 levers include seesaws and scissors.
Is a broom a class1 lever or a class 2 lever or a class 3 lever?
class 3
In what class of levers is the direction of the input force opposite to the direction of the output force?
In a class 3 lever, the direction of the input force is opposite to the direction of the output force. The fulcrum is located at one end, the input force is applied between the fulcrum and the output force, making the output force move in the opposite direction to the input force.
Which class of levers is the output force always less than the input force?
In a Class 3 lever, the output force is always less than the input force. This is because the effort force (input force) is situated between the fulcrum and the resistance force (output force). Examples of Class 3 levers include tweezers and human arm muscles.
What has a pivot point between a load and an input force?
The answer is: a lever.A lever is a simple machine that has a stick that pivots at a point called a Fulcrum.There are 3 types of Lever:First class lever: A first class lever is when a fulcrum is in the middle of the input force and the load. An example is a seesaw in the playground. When you press down the side of seesaw,(input force) the other side goes up. (load, output force) In the middle, there is a fixed point.Second class lever: A second class lever is where you have the load in the middle of the Fulcrum and the input force. An example would be a wheelbarrow. The basket in the middle is the load( also called the output force) the wheel at the end is the Fulcrum, and the handle that you press up and down is the input force.Third class lever: A third class lever is a lever that has a input force in between the Fulcrum and the Load. An example is a Hammer. The sharp part is the load(output force) the part you grab and swing is the input force, and the other end of the hammer is the Fulcrum.
What type of lever is the spring balance?
A spring balance is a type of class 2 lever. In this lever system, the fulcrum (pivot point) is at one end, the input force is applied in the middle, and the output force is at the other end. When weighing an object using a spring balance, the object exerts a downward force on the spring, causing it to stretch and give a reading.
