Answer:
Both end hinge-Pcr= 0.98 MN
Both end fix-Pcr=3.9 MN
Explanation:
E= 200 GPa
L=2 m
b=7 cm =70 mm
The critical load given as
For square section
Lets take column is hinge at the both ends :
Now by putting all the values
L'= L
Pcr=987371.6 N
Pcr= 0.98 MN
Therefore critical load = 0.98 MN
When both end fixed :
L' = 0.5 L
Pcr=3.9 MN
Therefore critical load = 3.9 MN
Answer:
I would say that it is forming.
Explanation:
Give brainliest if u can. :S
Material A = high elastic modulus and high melting temperature
Material B = low elastic modulus and low melting temperature
<u>Explanation:</u>
For material A, there is a high curvature to the inter-atomic potential, this is because of the strong nature of chemical bonding that exists in the material, and it takes a larger force for the change interatomic separation, which results in high elastic modulus and high melting temperature.
For material B, there is a short curvature to the interatomic potential, this is because of the wet nature of chemical bonding, and consequently, a much smaller force is needed for the change interatomic separation, which results in low elastic modulus and low melting temperature.
