Answer:
A train has at least 27 parts
Answer:
a) 23.39
b) 44977.08 N
c) 1922.92N
d) 454.31 MPa
e) 8.32 MPa
f)
Explanation:
a) fiber-matrix load ratio:
Let's use the formula :
b & c)
Total load is given as:
Fc = Ff + Fm
46900 = Fm(23.39) + Fm
46900 = 24.39 Fm
Actual load carried by matrix=
= 1922.92N=> answer for option c
Actual load carried by fiber, Ff:
Ff = 46900 - 1922.92
Ff = 44977.08 N => answer option b
d)
Let's find area of fiber, A_f.
Ac = Cross sectional area =300mm²
= 0.3 * 300 = 99 mm²
Area of matrix=
= 0.7 * 300 = 231 mm²
Magnitude of the stress on the fiber phase:
e) Magnitude of the stress on the matrix phase.
f) Strain in fiber =
Strain in matrix =
Composite strain =

Answer:
Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world.
