Reducing its temp. heat is the most common form of energy, and when a machine has friction, it is creating heat. by reducing the amount of friction, maybe by using some kind of lubricant between the objects, it will create less heat and thus use less energy input, with a higher input to out put ratio.

∙ 6y agoTo a large extent, this is due to friction. However, there are other reasons too; such as the Second Law of Thermodynamics, which doesn't allow heat engines - or, in fact, any process that is not infinitely slow - to be 100% efficient, even without friction.

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 percent of the Total Force is the Reserve Component?
50%
How is input and output shown on a force diagram?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
Is moving water considered to be a force?
Moving water exerts force. That is not the same as being a force.
Is moving water not considered to be a force?
Moving water exerts force. That is not the same as being a force.

What force stops machines from being 100 percent efficient?
Any mechanical action will waste energy as heat, therefore the work output is always less than the enegry input.
In 2000 18 percent of men were outside the labor force what percent of women were outside the labor force in 2000?
30 percent
In 2000 18 percent of men were outside the labor force what percent of women were outside labor force in 2000?
30 percent
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.
What percent do mexican's make up of the work force?
28 percent
What is the percent break down for labor force by occupation in Cambodia?
15 percent
What is it being When 100 percent of radiation bounces off of an object?
The radiation is being totally reflected.The object is absorbing momentum from the radiation, and is experiencinga force ... being 'pushed' ... in the direction that the radiation was travelingbefore the bounce.I'm not making that up.
What percent of women will be in the labor force?
Asian
What percent of labor force is there in Poland?
33%
What percent of airmen fly in the airforce?
Only one percent of the air force fly.
Is controlling the society through force of power the most efficient use of power?
Yes it is!
