What class lever would an engine hoist be?
An engine hoist would be a class 2 lever. The load (the engine being lifted) is between the effort (the force applied) and the fulcrum (the pivot point). This type of lever is useful for providing a mechanical advantage when lifting heavy objects.
Why is a third class lever useful for some tasks?
A third class lever is useful for tasks that require increased speed or range of motion. They provide a mechanical advantage, allowing for quick and agile movements while using less force. Third class levers are commonly found in the human body, such as in the bicep muscle, enabling efficient movement and dexterity.
Can a machine be use useful with a mechanical advantage of 1?
Yes, a machine with a mechanical advantage of 1 can still be useful by changing the direction of the force applied or by increasing distance moved, even though it doesn't multiply the force. Examples include a pulley or lever.
Why it is not possible to attain 100 percent efficiency in lever?
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
What is a practical use for a lever with a mechanical advantage of 1?
A lever with a mechanical advantage of 1 is useful for changing the direction of a force, such as when opening a door or lifting a light object like a book. It provides no multiplier to the input force, but can still be convenient for tasks requiring precise control or a change in direction.
What is the most useful machine?
the lever
What is the worlds most useful machine?
the lever
What are Useful facts and details of a first class lever?
Your arm can be considered a first class lever.
What is the world's useful machine?
What the most useful machine is, is a matter of opinion. Some would argue that the wheel is the most useful machine, and others would argue that the lever is the most useful.

What class lever is a pencil?
A pencil isn't a lever at all, unless you are using it to turn force into useful motion. If you use the pencil to write with, it's closer to being a needle reading a record, as it is dragged across a surface, leaving graphite which has broken off of the main core on the paper. For a first class lever, think of a see-saw. For a second class lever, think of a wheelbarrow. For a third class, think of a pair of nail clippers, or of your forearm.

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.
Is fishing rod first class lever?
3rd class lever
