Answer:
Geological engineers can help determine if the soil and structural stability in the building's location are satisfactory.
Explanation:
Geologic Engineering refers to a job which applies<em> geology to engineering</em>. This type of job focuses on the investigation of sites in response to<em> soil, rock </em>and <em>groundwater.</em> They help design the major structures for engineering works, thus, it is also their role <u><em>to know whether the building's soil and structural stability are satisfactory.</em></u> They determine <em>how much of the structure is a safe load for the soil it is standing upon.</em> They also test the strength of both rock and soil at different depths. This will help them know whether the location will be suitable for the skyscraper.
Answer:
procedure attached below
The material to be used will have a %Cw of 34.5%Cw which is < 40%Cw
Explanation:
<em>Given data:</em>
Minimum tensile strength = 865 MPa
Ductility = 10%EL
Desired Final diameter = 6.0 mm
20% cold worked 7.94 mm diameter 1040 steel stock
<u> Describe the procedure you would follow to obtain this material.</u>
assuming 1040 steel experiences cracking at 40%CW
<em>attached below is a detailed procedure of obtaining the material</em>
The material to be used will have a %Cw of 34.5%Cw which is < 40%Cw
Answer:
b). False
Explanation:
A refractory material is a type of material that can withstand high temperatures without loosing its strength. They are used in reactors, furnaces, kilns, etc.
Refractory materials are certain super alloys and ceramics materials.
Properties of refractory materials :
1. Refractory materials have high melting point.
2.They acts barriers between high heat zone and low heat zone.
3. The specific heat of refractory material is very low.
4. Refractories that have high bulk densities are better in quality.
Hence, Refractory materials have a very high melting temperature.
Answer:
Note that Air requires lesser work
Explanation:
Calculate for general work done
SInce Gas constant 'R' for: Neon = 0.4119KJ/kg.k , and Air = 0.287 kJ/kg·K
Calculate for work done of NEON
Calculate for work done of Air
