Any mechanical action will waste energy as heat, therefore the work output is always less than the enegry input.

What is the force that prevents all machines from being 100 percent efficient?

Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.


What must take place in order for work to be done?

Energy in some form must be expended, if the machine is 100 percent efficient the work done in Joules will equal the energy input in Joules, but of course machines are never 100 percent efficient, there are always some losses.


What is Force you put into simple machines?

Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.


Why does friction stops machines from not being 100 percent efficient?

Because friction causes a dissipation of heat energy and other kinetic energy. If you use the equation f = ma (Newton's law), where f= force, m= mass; a= acceleration, you can apply this to any machine and factor friction into the mass x acceleration equation. it will always decrease hypothetical force when applied with friction.


A measure of the amount a machine multiplies a force is its advantage?

The advantage of a machine is the ratio of the output force to the input force. It determines how much a machine amplifies or magnifies the input force applied to it. Machines with a higher advantage are more efficient at multiplying force.


How is force affect when a simple machine is used?

simple machines are used by being pulled or pushed


What kind of machines are astronauts trained on to simulate being in space?

They use centrifical force machines to duplicate high G-forces. They train underwater to simulate weightlessness.


What do simple machines do to make work easier?

Simple machines make work easier by reducing the amount of force needed to perform tasks or by changing the direction of the applied force. They achieve this by increasing the distance over which the force is applied or by allowing for a more efficient transfer of energy. Examples include levers, pulleys, and inclined planes, which can multiply force or allow for easier movement of heavy objects. By simplifying tasks, simple machines enhance efficiency and reduce effort.


Work is made easier when what changes the direction or size of the force needed to do the work?

Work is made easier when machines such as levers, pulleys, wheels, and inclined planes are used to change the direction or magnitude of the force applied, allowing for a more efficient use of energy. These machines help reduce the amount of force needed to perform a task by utilizing principles of mechanical advantage.


What is the force exerted by machines?

torque


What is the name of the machine of the force that prevents machines from operating at 100 percent efficiency?

The machine is called a governor. It regulates the speed and performance of machines to prevent them from operating beyond their design limits, protecting them from damage and ensuring stability.


When dealing with simple machines and compound machines how do you find the force?

you can measure
