Calculate the modulus of elasticity of the composite
I. In the longitudinal direction of the glass fibre
2. In the perpendicular direction of glass fibre
Answer:
1. 27.5876 GPa
2. 5.725 GPa
Explanation:
Given
Dimensions of the fibreglass is given by: 1.00 cm x 25.00 cm x 200.00 cm
Volume = 1 * 25 * 200 = 5000cm³
P1 = The volume fraction of the E-glass is 31%
P2 = The remainder 69% is Vinyl Ester
Volume of Vinyl Ester= 69% * 5000cm³ = 3450cm³
I. In the longitudinal direction of the glass fibre
Where
Modulus of elasticity of glass, E1 = 80 Gpa
Modulus of elasticity of vinyl ester, E2 = 4.04 Gpa
Modulus of elasticity = E1P1 + E2P2
Modulus of elasticity of vinyl esters = 31% * 80 + 69% * 4.04
Modulus = 24.8 + 2.7876
Modulus = 27.5876 GPa
ii. In the perpendicular direction of glass fibre
This is solved by
E1.E2/(P1.E2 + P2.E1)
= (80 * 4.04)/(31% * 4.04 + 69% * 80)
= 323.2/(1.2524 + 55.2)
= 5.725177317527687
= 5.725 GPa
Answer:
length of starter crack = 1.056
Explanation:
given data
temperature = 425 C
yield strength = 60%
Y parameter = 2.5
solution
we use here A 20 table so we get here value that is
Sy = 1360 MPa
Kic = 117.5 MPa 
so length of starter crack will be
a = 
.....................1
put here value and we will get
a = 
solve it we get
length of starter crack = 1.056
Answer:
The weather conditions do not suggest a blizzard. It is explained below.
Explanation:
wind_speed=randi([12 56],24,1);
visibility=randi([1 10],24,1)/10;
storm_data=[wind_speed,visibility];
save stormtrack.dat storm_data -ascii
clear
load stormtrack.dat
fprintf('Below is the storm data from the file stormtrack.dat \n');
disp(stormtrack)
wind_speed=stormtrack(:,1);
visibility=stormtrack(:,2);
L=length(wind_speed);
count=0;
i=0;
while count<4 && i<L
i=i+1;
if wind_speed(i)>=30 && visibility(i)<=0.5
count=count+1;
else
count=0;
end
end
if count==4
fprintf('The weather conditions suggest a blizzard.\n')
else
fprintf('The weather conditions do not suggest a blizzard.\n')
end

Answer:
Simply put, the grade or grading around your house is the level of the ground. The ground level and how it's graded is the deciding factor of where storm water will flow.
