Question 4 of 10
4. Question
On the off chance that a heater is to warm temperatures around 1500°C, which of the accompanying material for warming components ought to be chosen?
Correct
The softening purpose of Eureka is 1221 to 1300 °C. The softening purpose of Kanthal is 1,425 °C. The softening purpose of Nichrome is 1400 °C. Molybdenum mixes (about 14% of world creation of the component) are utilized in high-pressing factor and high-temperature applications as colors and impetuses. The liquefying purpose of the platinum-molybdenum carbon compound is around 3000°C.

Question 5 of 10
5. Question
Which of the accompanying will occur if the thickness of the stubborn mass of the heater is expanded?
Correct
In a heater we need to have high warmth move inside the heater; nonetheless, we don’t need any warmth misfortune through the heater divider. Consequently to forestall the warmth move from the heater to the air an awful warmth conductor or an awesome warmth protector is required. On account of the heater, the divider is set up by different layers of hard-headed materials to limit the warmth misfortunes. In this way, divider protection is needed to limit the warmth misfortune from the framework to the climate or warmth acquire from the climate to the framework.

Question 6 of 10
6. Question
Which of the accompanying techniques is best for inspecting surface imperfections on the castings?
Correct
Visual assessment is a kind of non – damaging testing method that gives a method for distinguishing and analyzing the assortment of surface imperfections, for example, surface completion, discontinuities, and surface breaks on the castings. This strategy is exceptionally modest and broadly utilized in light of the fact that a large portion of the surface deformities and unpleasantness can be noticed without any problem.
