What is the stationary point on a lever?
The stationary point on a lever is the point at which the lever pivots or rotates. It is often referred to as the fulcrum and serves as the fixed point around which the lever moves. Adjusting the position of the fulcrum can change the mechanical advantage and leverage of the lever system.
How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
What is the fulcrum between effort and resistance?
a 1st class lever there are 3 types of levers, 1st 2nd and 3rd class. 1st: fulcrum between effort and resistance 2nd:resistance between fulcrum and effort 3rd: effort between fulcrum and resistance Fulcrum = a pivot point on a lever. Effort = force applied on lever Resistance = load 1st example:see-saw/scissors 2nd example:wheelbarrow/car door 3rd example:someone raking/ hockey stick being usued
Does a pulley have a fulcrum?
No, a fulcrum is the pivot point for a lever
What simple machine can change the strength of force?
A lever is a simple machine that can change the strength of force. By adjusting the position of the pivot point (fulcrum), a lever can increase or decrease the force needed to move an object. For example, a longer lever provides more mechanical advantage, requiring less force to lift an object.

What is the chemical advantage of lever?
Levers can amplify force, allowing small input forces to exert larger output forces. This is due to the principle of mechanical advantage, which is based on the lever arm lengths. The position of the fulcrum can also change the direction of the force applied.

What is the major of advantage of pushpull steering from the low hand position?
It makes it more easy to change gear

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
Which class of lever does not multiply input force?
A class 1 lever does not multiply input force. In this type of lever, the fulcrum is positioned between the effort force and the load, resulting in no mechanical advantage gained. An example of a class 1 lever is a see-saw.
What advantage is there in having a wheelchair that allows people to change position?
Changes of position relieve pressure and can help lessen the development of skin irritation. Changing position can also help some people breathe more easily.
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
What do fulcrums help?
A fulcrum is the point of tuning for a lever. Since a fulcrum is essential for a lever, it does not help but rather is needed. The lever and fulcrum are used to move or hold objects. Levers can be used change the amount of force needed to alter a system of load, lever, and effort. The position of the fulcrum determines the force needed to change the natural equilibrium. There are three classes of levers divided in accordance to the position of the fulcrum. The first class of lever is typically used in a gravitational field with a load at one end of the lever, the fulcrum closer to the load than the middle of the lever, and a force applied near the other end of the lever. The important point is that the fulcrum is between the two forces and on the opposite side. If the lever is longer on the force side, the force needed to move the load is less than the weight of the load, but the load travels a smaller distance than the applied force point moves. This would be used possibly to lift an heavy object. By placing the fulcrum close to the point of force, the load moves farther than the applying force. This can be demonstrated by observing a trebuchet (commonly referred to as a catapult) The second class of lever places the load and the force on the same side of the fulcrum with the load closer to the fulcrum than the applied force. An example of this is the wheelbarrow. Again, the force needed to lift the load is less than the weight of the load. The third class of lever places the force between the fulcrum and the load. Examples of uses for this are chopsticks or ice tongs.
