For surfaces that are perpendicular to one direction, the stress magnitude is greatest, and for surfaces that are parallel to that direction, the stress magnitude is zero.
Stress is the applied force or system of forces that tends to deform a body from the viewpoint of loading. Stress is the internal distribution of forces within a body that balance and respond to the loads given to it from the viewpoint of what is happening inside a material. Stress is a measurement of how a substance reacts to external influences. It is merely a ratio of the material's cross sectional area to the external forces. Stress (S = R/A, where S is the stress) is the ratio of force to area.

Answer: the critical stress for the sodalime glass = 5.7MPa
Explanation:
Ist Step
we Calculate half length of internal crack as
2a =0.8 mm
a = 0.8/2 = 0.4 mm
Changing to meters becomes = 0.4 / 1000 =0.0004m
2nd Step
Now the critical stress required for the propagation of the internal crack can be calculated using the formulae
Critical Stress (σc) = (2 E γs/ πa) 1/2
where E= modulus of elasticity
γs= specific surface energy for soda–lime glass
a= Length
= (2 x 69 x 10 ^9 x 0.30/ π x 0.0004)1/2
=
= 5,739,407.8= 5.7 x 10^6 N/m^2
= 5.7MPa

Explanation:
<em>Early Stone Age</em>, or Paleolithic, <em>middle</em> and <em>Late Stone Age</em>, or Neolithic
Copper Age or Bronze Age also are part of the stone age
Answer:
Both Technician A and Technician B
Explanation:
Information regarding the depressurization of the of the electronic brake control (EBC) is contained in the service manual. Information regarding the depressurization of the accumulator should be researched and information based on the manufacturers information should be followed
Other steps required in depressurization are;
The ignition is placed in the off position
The ABS fuse should be removed from the fuse box
Firmly apply the brakes for at least 40 times
The brakes should be applied to verify that there is no power assist remaining. The brakes should be further pumped for an additional 10 times if there is still power assist.
