Gauge redundancy arises in physical theories when certain configurations are physically equivalent. Symmetry, on the other hand, refers to invariance of a physical system under a transformation. In gauge theories, the gauge redundancy leads to local symmetries that leave physical observables unchanged.

What is the net force on the force gauge?
If the force gauge isn't moving, the the net force must needs be zero.
How you calculate deflection of a dial gauge of least count 01mm?
To calculate the deflection of a dial gauge with a least count of 0.01mm, you read the measurement indicated by the needle on the dial gauge after it has been set to the initial position. The deflection is the difference between the initial reading and the final reading on the dial gauge. Deflection = Final reading - Initial reading.
What is the difference between instrument and gauge?
An instrument is a device used for measuring or monitoring a particular quantity or level, while a gauge specifically refers to a device used for measuring pressure or depth. In general, an instrument has a broader application, encompassing various types of measurement devices, while a gauge is more specialized in its use.
Difference between photohelic and magnahelic gauge?
A photohelic gauge measures and displays pressure differentials and can also control devices based on those readings. A magnahelic gauge, on the other hand, measures positive, negative, and differential pressures but does not have control capabilities.
Difference between pressure gauge and vacuum gauge?
A pressure gauge measures the pressure of a fluid or gas relative to atmospheric pressure, while a vacuum gauge measures pressures below atmospheric pressure. Pressure gauges typically have a positive scale, while vacuum gauges have a negative scale. Both gauges provide crucial information for monitoring and controlling pressure systems.
What is difference between 20-gauge and 28-gauge?
20 gauge is larger
What is the difference between a 20 gauge and a 12 gauge?
The size of the bore.
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
What is the difference between a twelve gauge and twenty gauge shotgun?
Size of the bore.
What is difference between 16 and 18 gauge steel?
16 gauge is thicker than 18 gauge.
What is the difference between 12 gauge and 20 gauge shotguns?
12 has a bigger bore.
What is the difference between a 410 and a 12 gauge shotgun?
Size of the bore. 12 gauge is bigger.
What is the difference between a 12 gauge shotgun and a 20 gauge?
Size of bore, size of ammuntion
What is the difference between OO and HO gauge?
They are different sizes.
What is the difference between 22 gauge steel and 26 gauge?
26 gauge is your common metal mailbox 26 gauge is comparable to the skin on an elevator door.
What is the difference between a 17 gauge and 20 gauge brass bath waste drain?
The metal of the 17 gauge waste drain is thicker than the 20 gauge.
