Simple Machines (engineering)
A simple machine is a mechanical device that can help you change the force applied to help do more work easier. There are six simple machines: Wheel and axle, pulley, inclined plane, wedge, and screw.

Why do machines help us do work?
Machines help us do work by increasing efficiency and reducing the physical effort required for tasks. They can perform repetitive, complex, or heavy tasks more quickly and accurately than humans. By automating processes and enhancing our capabilities, machines allow us to focus on more creative and strategic activities, ultimately improving productivity and innovation.
What is the term for a tool that makes work easier by changing the size or the direction of force?
machine

Fax machines are still used because they are faster than a courier or mail to send a document, and give a "confirmaiton of message received" (a confirmation page) that email does not do (email has an option to have a read receipt, but that is only if the receiving party agrees to send the read receipt).
What are all the simple machines in a pizza cutter?
A pizza cutter primarily incorporates two simple machines: the wheel and axle, and the lever. The circular blade acts as the wheel, rotating on the axle to slice through the pizza. Additionally, the handle of some pizza cutters can function as a lever, providing leverage to apply pressure and maneuver the cutter effectively. Together, these simple machines enhance the efficiency of cutting pizza.
What is the difference between a lever and a pulley?
A lever is an adaptation of a stick or tree branch. A pulley is an adaptation of a wheel.
How do the wedges make work easier?
Wedges make work easier by converting a force applied in one direction into a force exerted in a perpendicular direction, effectively splitting or lifting objects. This mechanical advantage allows a smaller input force to accomplish tasks that would require significantly more effort if done directly, such as cutting or prying. By increasing the distance over which the force is applied, wedges also reduce the amount of force needed to achieve the desired effect. Overall, they enhance efficiency in various applications, from cutting tools to doorstops.
Where is the effort load fulcrum in a fishing rod?
In a fishing rod, the effort load fulcrum is typically located at the point where the rod is held, often near the handle. This point acts as the pivot around which the rod bends when a force is applied to the tip, such as when reeling in a fish. The design allows for efficient leverage, enabling the angler to exert force and control the fish with minimal effort. The distribution of weight and resistance along the rod also influences its performance and sensitivity.
