**Answer:**

**shear plane angle Ф = 26.28°**

**shear strain 2.20 **

**Explanation:**

given data

angle = 16°

chip thickness t1 = 0.32 mm

cut yields chip thickness t2 = 0.72 mm

solution

we get here first chip thickness ratio that is

chip thickness ratio = ................. 1

put here value

chip thickness ratio =

chip thickness ratio r = 0.45

so here shear angle will be Ф

tan Ф = ............2

tan Ф =

tan Ф = 0.4938

**Ф = 26.28°**

and

now we get shear strain that is

shear strain r = cot Ф + tan (Ф - α ) ................3

shear strain r = cot(26.28) + tan (26.28 - 16 )

**shear strain r = 2.20**

Answer:

mantle rocks begin to melt

Explanation:

melt when temperature raises, pressure lowers or water is added

**Explanation:**

Mid-wing configuration places wings exactly at midline of airplane which means at half of height of fuselage. These airplanes are well balanced and also they have a large control surface area.It is the best option aerodynamically as these planes are streamlined much more and also has low interference drag as compared to the high and the low wing configurations.

The mid-wing has almost neutral roll stability that is further good from prespective of the combat as well as the aerobatic aircraft as mid-wing allows for performance of the rapid roll maneuvers with the minimum yaw coupling.
