Answer:

There are 7 types of residential circuits.

Explanation:

Resendential Circuits means circuits used while wiring residential buildings. There are 6 different types of resedential wirings. Outlet Circuit, Lighting Circuit, Room Circuit, Special Circuit, 240 Volt Circuit, GFCI Circuit, and AFCI Circuit.

All the basic circuits of resedential building are connected with an outlet circuit, and this type of circuit have 15 - 20 amps of pole breaker. Lightening Circuit is only for the wiring of lights in the complete resedential building, so that if anything goes wrong in lights, we could inspect that much only.

Sometimes, even there is a separate circuit for Rooms, and in resedential building, each and every room have different circuit. There are many appliances which require very high wattage like furnaces, or refrigerator.

For them, special circuit is down and pole breaker is generally upto 30 apms. More heavy duty appliances are wired by 240 Volt Circuit, and GFCI and AFCI Circuits are for safety measures and to cutoff all the circuits if anything goes wrong.

Explanation:

Step1

In the stress-strain curve of any material, the yield stress is the maximum stress at which material starts yielding.

Step2

Young’s modulus is the constant of proportionality of stress and strain according to hooks law. It is the slope of the slope of the stress-strain curve of the any material under proportional limit.

Step3

Ultimate tensile stress is the maximum stress that induced in the material under application of load.

Step4

Toughness is the strain energy per unit volume up to the fracture point of the stress-strain diagram of any material. This is the area under the curve of stress-strain.

Step5

Point of necking is the point where any material starts necking under application of load in necking region of the stress-strain curve.

Step6

Fracture point is the last point of the stress-strain curve where component fractures under application of load.

All the parameters are shown in below stress-strain curve:
