How does a strain gauge work?
The metal foil is a resistor---it conducts electricity but also resists its flow somewhat. When the sheet is bent one way it stretches the foil slightly, making it longer and thinner. This raises its resistance, since the electricity has further to go and a more constricted path to follow. On the other hand, when the sheet is bent in the other direction it compresses the foil, making it shorter and wider and lowering the resistance. Because the foil strip is so long, even slight strains will cause fairly big changes in the resistance, which will be picked up by the Wheatstone bridge.
What are the uses of equations?
They are very important in many areas such as maths and physics. They are used to work out unknown's. For example in physics if you know the current through a circuit, and the total resistance, and you need to find out the voltage, you can use the equation: Voltage= current * resistance, to work out.

What is the meaning of resistance force?
Resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pound-force. Resistance force is used to calculate the work output using the equation: Work output = Resistance force * resistance distance

Is resistance to antibiotics permanent?
No, resistance to antibiotics is not permanent. However, once you have a resistance, that antibiotic will no longer work for specific infections.
