To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
A toothbrush is not a simple machine, it does not work on the principle of levers, effort, and load. It's not a machine at all in mathematical terms. A "machine" is that which performs "work", i.e. transfers or converts energy. You arm moving the toothbrush is a machine by this definition, however.
A lever
A fulcrum.
Lever -- load, fulcrum, force
A wheelbarrow uses a lever as a simple machine to lift a load. The handle of the wheelbarrow acts as the lever, allowing the user to exert a force to lift the load placed in the container.
A Inclined Plane Can Help You Raise A Load Or A Pulley System.
It is called LOAD.
inclined plane
the law of the machine is an expression which gives the relationship between the load on a machine and the applied effort
This simple machine is likely a lever, where the load is on one end and the applied force is on the other. By using a lever, you can lift a load that is double the weight of the force applied due to the mechanical advantage gained.
A crane utilizes a combination of simple machines, but the primary one involved in lifting a load is the pulley. The pulley system allows the crane to lift heavy loads with relatively less effort by applying force over a distance.
Effort in a simple machine refers to the force applied by a person or machine to operate the machine. It is the input force needed to overcome resistance and move the load in the machine. The effort required depends on the type of machine and the mechanical advantage it provides.
The force to be overcome by a simple machine is called the input force or effort force. This is the force applied to the machine in order to make it work against the resistance force or load.
