Answer:
B.29
Explanation:
In general purpose acme thread:
Nominal depth of thread=0.5
Included angle =29 degrees
Generally Acme thread are following types
1.General purpose(G) Acme
2.Centralizing(C) Acme
3. Stub Acme
Centralizing(C) Acme threads have tighter tolerance during manufacturing as compare to General purpose(G) Acme threads.
Answer:
A geological engineer
Explanation:
The field of geological engineering is concerned with geology, civil engineering and area of mining , geography and forestry.
Geological engineers apply their knowledge of earth science to solve human problems. Such as creating an equipment using science that can aid in solving the challenge in separating coal from dirt components in an environmental friendly manner.
Geological engineers investigate this that are connected to the earth such as mines, roads, quarries , pipelines, petroleum products, forests and building projects. They also perform surveys on effects of landslides and earthquakes.
Answer:
C. Welded contacts on the thermostat
Explanation:
Any fault that keeps the heating element heating when it should not is a fault that will cause the symptom described. The details <em>depend on the design of the brewer</em> (not given).
"A short at the terminals" depends on what terminals are being referenced. The device on-off switch terminals are normally connected together when the brewer is turned on, so a short there may not be observable.
"Welded contacts on the thermostat" will have the observed effect if the thermostat is the primary means of ending the brewing cycle. If the thermostat of interest is an overheat protective device not normally involved in ending the brewing cycle, then that fault may not cause the observed symptom.
__
If the heating element is open-circuit, no heating will occur. A gasket leak may cause a puddle, but may have nothing to do with the end of the brewing cycle. (Loss of water can be expected to end boiling, rather than prolong it.)
