Explanation:
Given that:
The direction of the applied tensile stress =[001]
direction of the slip plane = [01]
normal to the slip plane = [111]
Now, the first thing to do is to calculate the angle between the tensile stress and the slip by using the formula:
where;
= directional indices for tensile stress
= slip direction
replacing their values;
i.e = 0 ,
= 0
= 1 &
= -1 ,
= 0 ,
= 1
Also, to find the angle between the stress [001] & normal slip plane [111]
Then;
replacing their values;
i.e = 0 ,
= 0
= 1 &
= 1 ,
= 1 ,
= 1
However, the critical resolved SS(shear stress) can be computed using the formula:
where;
applied tensile stress 13.9 MPa
∴

Explanation:
Given that :
The initial volume of water = 1000.00 mL = 1000000 mm³
The initial temperature of the water = 10° C
The height of the water column h = 1000.00 mm
The final temperature of the water = 70° C
The coefficient of thermal expansion for the glass is ∝ =
The objective is to determine the the depth of the water column
In order to do that we will need to determine the volume of the water.
We obtain the data for physical properties of water at standard sea level atmospheric from pressure tables; So:
At temperature the density of the water is
At temperature the density of the water is
The mass of the water is
Thus; we can say ;
⇒
Thus, the volume of the water after heating to a required temperature of is 1022400 mm³
However; taking an integral look at this process; the volume of the water before heating can be deduced by the relation:
The area of the water before heating is:
The area of the heated water is :
Finally, the depth of the heated hot water is:
Hence the depth of the heated hot water is
