A screw is a simple machine that helps to fasten pieces of wood together. It consists of a cylindrical shaft with a helical ridge, or thread, which allows it to be driven into the wood. When turned, the screw creates a tight grip by pulling the pieces of wood closer together, providing stability and strength to the joint.
Simple machine helps us to increase the power and force for change.
A 'LEVER'.
A simple machine that helps you tighten shoelaces is a pulley. When you pull on the laces, they wrap around a small wheel, allowing you to apply force more effectively to tighten them. This mechanism makes it easier to secure the laces without having to exert as much effort directly.
The pivot point of a small simple machine, often referred to as the fulcrum, is the fixed point around which the machine rotates or balances. It plays a crucial role in determining the mechanical advantage of the machine, as it affects the input and output forces. For example, in a lever, the position of the fulcrum relative to the load and effort influences how easily the machine can lift or move objects. Understanding the pivot point helps in optimizing the machine's efficiency and effectiveness in performing work.
A slide is an example of an inclined plane, which is a type of simple machine. It allows objects to move from a higher elevation to a lower one with reduced friction, making it easier to slide down. The slope of the slide helps convert potential energy into kinetic energy as the person or object descends.
A board pin is a type of fastener and can be considered a type of simple machine known as a wedge. The pointed end of the pin helps it exert force to push materials apart, making it easier to fasten objects together.
It is a simple machine and is also a type of lever! I hope this helps : )
A wheel and axle.
simple machine
No, it's a compound machine.
Yes, a wedge is considered a simple machine, not a compound machine. It is a simple machine because it is a basic mechanical device that helps to make work easier by changing the direction or magnitude of a force.
A door knob is considered a simple machine because it helps to transmit force to open or close a door by rotating.

A tape dispenser is a lever simple machine. When you press down on the lever, it helps cut and apply the tape smoothly.
Stairs are considered a simple machine. They are an inclined plane that helps to change the direction of force needed to move objects or people vertically.
A 'LEVER'.
They are called compound machines. :)Hope that helps
