What is the minimum bend radius of a loom adequately supported at a terminal block?
- 10 * diameter
- 8 * diameter
- 3 * diameter
why is 3*d and not 8*d?
What non-destructive testing method requires little or no part preparation, is used to detect surface or near-surface defects in most metals, and may also be used to separate metals or alloys and their heat-treat conditions?
- Eddy current inspection.
- Magnetic particle inspection.
- Ultrasonic pulse inspection.
isnt eddy current inspecction method only for internal cracks?Why does it mention here that it is used to detect"surface and nearsurface"?
When tapping blind holes
- a set of three taps is used.
- a set of two taps is used.
- a single bottoming tap is used.
what does 3 taps mean?
Springs are manufactured from
- high carbon alloy steel with high strength requirements.
- low carbon alloy steel with high strength requirements.
- high carbon alloy steel with low strength requirements.
i think in module 6 it literally said that the correct answer was "high carbon alloy steel with low strength requirements" am i wrong?Or did i get confused?
Which contains the least amount of heat energy?
- Both 1 kg of ice at 0 degrees C and 1 kg of water at 0 degrees C have the same amount of heat energy.
- 1 kg of water at 0 degrees C has less total heat energy than 1 kg of ice at the same temperature.
- 1 kg of ice at 0 degrees C contains more total heat energy than 1 kg of water at that temperature.
Enthalpy (i.e. heat) of water = Enthalpy of ice + latent heat.
I think the answer should be that ice contain least amount of heat energy. Because ice will need to get additional heat energy to change the state/phase of the substance (ice to water).
