the relationship between them is that the machines have friction that makes the machine goes

With most machines the desired output is mechanical or electrical energy. Friction produces heat energy which is a waste and therefore inefficient.

Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.

It lowers the mechanical advantage of the machine. The machine will not do as much "work".

User Avatar

Efficiency of the machine is reduced due to loss of energy by friction.

User Avatar

Because too much friction can damage the simple machines that make up the compound machine.

The smaller amount of friction a machine has, the more efficient it becomes.

energy used for the machine will get lost as heat .machine parts will get worn out.

In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.

Many Machines either run on, or are run by electricity. Remove the electrical parts or the electrical supply and the machine would stop.

Nope - friction slows machines down.

frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.

An Electric Transformer is an electrical devise used to transform voltage. As it has different parts which achieve a purpose it can be classified as a machine.AnswerYes, transformers are classified as electrical machines.

they reduse the friction between the machine parts.

User Avatar

Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.

All photocopy machines use electrical energy.

Machines heated up due to the friction caused due to their running internal parts. That's's why machines are oiled or greased to reduce friction and to produce less heat

FIRST THING I WANT TO KNOW THAT WHETHER YOU ARE TALKING ABOUT INDUCTION MACHINE OR SYNCHRONOUS MACHINE? IN INDUCTION MACHINE, RATIO OF VOLTAGE TO FREQUENCY MUST BE SAME FOR CONSTANT TORQUE. IN THESE CASE AS YOU CAN SEE, V/f RATIO IS NOT CONSTANT THEN INDUCTION MOTOR WOULD NOT RUN.

Machine without any friction is an ideal machine so an ideal machine cannot have friction.
