The word is treadle.
Example of a lever.
When you pry open a can of paint, you are using a lever, which is a type of simple machine. The lever consists of a rigid bar (like a paint can opener) that pivots around a fulcrum, allowing you to exert force on one end to lift the lid on the other end. This mechanical advantage makes it easier to open the can with less effort.
A simple machine that would lift a rock is a lever. By using a lever, you can apply force to one end, which allows the rock to be lifted on the other end. The lever amplifies your input force, making it easier to move heavy objects. Another option is a pulley, which can also effectively lift a rock by distributing the weight and reducing the effort needed.
No, a fridge is not a lever. A lever is a simple machine that consists of a rigid bar pivoted around a fulcrum to lift or move loads. A fridge, on the other hand, is an appliance designed for refrigeration and food preservation, using a refrigeration cycle rather than mechanical leverage to operate.
A garden hose can be considered a type of simple machine known as a lever. When using a hose, the user applies force at one end to create water pressure, allowing the hose to direct the flow of water to a specific area. The hose itself acts as a lever that amplifies the force exerted, making it easier to transport water over a distance. However, it's important to note that while it has lever-like qualities, a garden hose is more accurately described as a tool rather than a classic simple machine like a lever, pulley, or inclined plane.
Using a treadle. (a lever worked by the foot that imparts motion to a machine.)
A lever
If you are pulling a nail out of wood, you are using a lever as a simple machine. By applying force to one end of the lever (the nail), you are able to lift the nail out of the wood using the principle of torque.
A lever worked by a foot is called a foot pedal. It is a mechanism used to control or activate a device using the pressure from a person's foot.

A Lever
A compound machine consisting of a lever and wedge would typically involve using the lever to apply force on the wedge. For example, using a lever to push down on a wedge to split wood. The lever amplifies the force applied to the wedge, making it easier to perform tasks that would be difficult with just the wedge alone.
Using an incline lever row machine for strength training can help improve back and arm muscles, enhance posture, and increase overall upper body strength.
Blinds operate using a pulley system, making them an example of a class 1 lever simple machine. This lever allows the blinds to be raised and lowered with minimal effort by applying force at one end of the lever.
A barber chair is a type of lever simple machine. By using a lever mechanism, a barber can easily adjust the height of the chair to accommodate different clients.
A bike is a simple machine, because it has a wheel and axle.
Using a lever row machine for strength training can help improve muscle strength and endurance in the back, shoulders, and arms. It also allows for controlled and targeted movements, reducing the risk of injury. Additionally, the machine provides a consistent resistance throughout the exercise, leading to more effective muscle development.
