Answer:
shearing deformation has to do with change in shape not length, so it should be neglected. As for the data obtained in this experiment, it strongly agree with the statement as all values in the experiment were quite close and were under the target value. Greater than ten percent error.
It is given that volume is constant i.e 3000 L.
So,
Now,
Putting all values in above equation, we get :
Therefore, the new pressure will be 23.20 MPa.
Hence, this is the required solution.
Answer: False
Explanation: Sandwich materials are usually in composite material form which has a fabrication of two thin layers which are stiff in nature and have light weighing and thick core .The construction is based on the ratio that is of stiffness to the weight .Therefore, the density of the material in the core is not high and are only connected with the skin layer through adhesive .So the given statement is false that sandwich materials typically use a high density core with non- structural cover plates.
Answer:
0.59
Explanation:
based on Lever's phase rule, we can find the fraction of the α phase in the structure using the following formula:
where
= mass fraction of element B in the entire alloy or mixture = 40%
= mass fraction of element B in the β phase = 90%
= mass fraction of element B in the α phase = 5%
hence we have
∴ The fraction α phase in the structure is ≈ 0.59
