Answer:
volume fraction of fibers is 0.4
Explanation:
Given that for the aligned carbon fiber-epoxy matrix composite:
Diameter (D) = 0.029 mm
Length (L) = 2.3 mm
Tensile strength (
) = 610 MPa
fracture strength (
) = 5300 MPa
matrix stress (
) = 17.3 MPa
fiber-matrix bond strength (
) = 19 MPa
The critical length is given as:
Since the critical length is greater than the length, the aligned carbon fiber-epoxy matrix composite can be produced.
The longitudinal strength is given by:
making Vf the subject of the formula:
Vf is the volume fraction of fibers.
Therefore:
volume fraction of fibers is 0.4
Answer:
$958.25
Explanation:
PV = FV(1 +r)^(-t) . . . . present value of an amount earning rate r compounded annually for t years
PV = $3000(1.08^-5) ≈ $2041.75
The equivalent present value is $2041.75.
__
This amount is less than the offered amount by ...
$3000 -2041.75 = $958.25
She should pay you $958.25 less in order to make the offers equivalent.

Answer:
The major and minor stresses are as 2060.59 psf, -310.59 psf and 1185.59 psf.
Explanation:
The major and minor principal stresses are given as follows:
Here
is the normal stress which is 1750 psf
is 0
is the shear stress which is 800 psf
So the formula becomes
Similarly, the minimum normal stress is given as
The maximum shear stress is given as
Answer:
The correct option is;
D. Electric meter
Explanation:
An electric meter is a metering device that is used for the measurement of the electric power consumption of an electrical powered tools, a living space or a building
Electric meter readings are used by electric utility company to sell electric power to consumers at a given rate such that it allows the electric utility company to receive payment for the total power supplied, and for the consumer to regulate the amount of power consumed
The electric meters are usually calibrated in kilowatt hour (kWh) and prepaid meter displays the amount of units of power bought, while post paid meters are usually read once each billing period which is usually one month.
