Are you referring to simple machines?

machine
I it's Simple machine.. had this exact same Question on my Test and i got it right
harold jay newton is the best way of answer is called "oten,belat"
A Simple Machine
Pulleys and levers both change both.
A converging lens changes the direction of light through the process of refraction. A lens is a device that uses refraction to bend light to form an image.
The ratchet is a device which applies a pressure by slipping at a predetermined torque and thus prevents the spindle from moving further.
A resistor resists the flow of current in a circuit but a transistor changes the amount of current through a device. This is called current magnification. Field effect transistors FETs and MOSFETs (metal oxide semiconductor field effect transistor) may also change the amount of current to a load lastly a variable resistor or a potentiometer or a variable resistor can variate the amount of current at your will
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.
Half The time. In Physiology power is the amount of work done per unit of time, obviously you are a student so think kid.

Machine
It is an effort machine
Those kinds of devices are called machines.
It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
A converging lens changes the direction of light through the process of refraction. A lens is a device that uses refraction to bend light to form an image.
* a device that responds to mechanical strain. with a small change in resistance. ... * device for determining the amount of strain (change in dimensions) when a stress is applied
LED = Light-Emitting Diode This is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device.
Not in normal circumstances. A diode is an electonic device that allows current to flow freely in only one direction.
a device which changes ac to dc is known as 'conevrter' a device which changes dc to ac is known as 'inverter'
