Question

state the principle of an ideal machine for class 10

Answer 1

ideal machine is originally an hypothetical mechanical system in which energy and power are not lost or dissipated through friction, deformation...... the output energy is equal to the input energy. Therefore, mathematically we can express it as input=output .....this is the principal of an ideal machine

Answer 2

THE ENERGY INPUT=THE ENERGY OUTPUT
WHICH CAN NEVER OCCUR.
BCOZ SOME ENERGY IS LOST TROUGH THE FRICTIONS IN THE MACHINE.
