What effect does moving the fulcrum have on a lever?
Moving the fulcrum changes the mechanical advantage of the lever. Placing the fulcrum closer to the load increases the force needed to lift the load but allows for greater distance and speed. Moving it closer to the effort reduces the force needed but decreases the distance and speed.
A lever is defined as a rigid bar that turns around an axis of rotation or fulcrum?
Correct, a lever is a simple machine consisting of a rigid beam or bar that pivots around a fixed hinge or point called the fulcrum. Levers are used to amplify force, gain mechanical advantage, or change the direction of an applied force. They are commonly found in everyday objects such as seesaws, scissors, and crowbars.
Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
What part of a lever is the point where the lever rest?
fulcrum
What are the defferent classes of lever?
The three classes of levers are defined by the relative positions of the fulcrum, effort (force applied), and load (resistance to be overcome). In a first-class lever, the fulcrum is located between the effort and the load (e.g. seesaw). In a second-class lever, the load is between the fulcrum and the effort (e.g. wheelbarrow). In a third-class lever, the effort is between the fulcrum and the load (e.g. tweezers).
What effect does moving the fulcrum have on a lever?
Moving the fulcrum changes the mechanical advantage of the lever. Placing the fulcrum closer to the load increases the force needed to lift the load but allows for greater distance and speed. Moving it closer to the effort reduces the force needed but decreases the distance and speed.
What are torques?
Torque is a force that is applied to a lever. (Imagine a rachet. As you tighten a bolt, you push on the handle, which is essentially a lever. This lever exerts torque on the bolt, causing it to spin) Torque is defined as T = r cross F, or just R X F. Basically, if you multiply the force by the distance of the force from the central point on the object you are trying to rotate, you have torque.
What is the answer to a wheel and axle?
There is no specific answer to a wheel and axle. A wheel and axle is actually defined as a lever that spins. Generally, the wheel rotates around the axle for the proper usage of certain machines.

Why is the fulcrum in a lever important?
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
