⦁ Write your answers to the following blanks.The Charpy impact experiment is through the process of obtaining the energy of the material ② by using the difference in ① energy before and after the impact. ② The lower the energy, the ③ behaves, and the higher the ④, the more it is destroyed.

Yield strength, ultimate tensile strength, linear coefficient of thermal expansion, modulus of elasticity (E), proportional limit, and rupture strength are all examples of mechanical properties of engineering materials. O True False A non-destructive test is any examination of an object in any manner which will not impair the future usefulness of the object. Non-destructive tests include: magnetic-particle, impacting testing, radiography, eddy current, and fluorescent-penetrant. O True O False One way to make a metal stronger is to increase the metal's grain size. O True O False --- OL T A metal that has a crystalline structure is called amorphous. O True O False

How does the Deformation of a body occur?

1. Why does a surface composed of a particular material get dirtied? 2. Why do engineering metals and alloys break, despite the fact that they can't be prevented from doing so?   Please explain in full detail! Thank you

It's saying this is not correct. Thank you for your help.

Power is supplied at the rate of 0.40 hp for 2 min in drilling a hole in a 1.0 lb brass block. (a) How much heat is generated? (b) What is the rise in temperature of the brass if 75% of the heat generated warms the brass? What happens to the other 25%? (don't change the hp, lb)

answer the following questions

It is still saying that is not correct. I have tried this practice problem over and over and that is the only part that it keeps saying is incorrect. the negative and units are correct. I appreciate your help.

DIRECTION: Identify the following term.  3. It is the study of the relationship between the external loads applied to a body and the stress and strain caused by the internal loads within the body.
