Answer:
d=13.81 mm
Explanation:
Given that
P = 15 KN ,L = 50 m
E= 200 GPa
ΔL = 25 mm
σ = 150 MPa
Lets take d=Diameter
There are we have two criteria to find out the diameter of the wire
Case I :
According to Stress ,σ = 150 MPa
P = σ A
By putting the values
d= 11.28 mm
Case II:
According to elongation ,ΔL = 25 mm
d=13.81 mm
Therefore the answer will be 13.81 mm .Because it satisfy both the conditions.
Answer:A) Risk(R)= $1000
B) There is justification for spending an additional cost of $100 to prevent a corrosion whose consequence in monetary terms is $1000
Explanation:R= Risk,
P=Probability of failure
C= Consequence of failure
Mathematically, R=P ×C
10 out of 1000 carbon-steal products failed
Probability of failure= 10/1000 =0.01
The consequence of failure by corrosion given in monetary term =$100,000
Risk of failure = 0.01 × $100,000
R=$1000
For both NPN and PNP this is true:
The base is between the collector and the emitter.
The correct answer for the first one is A) Breaking rocks into smaller pieces. The correct answer to the second one is A) It has more energy. Hope this helps.
<span>First law of thermodynamics. This conservation law states that energy cannot be created or destroyed but can be changed from one form to another. In essence, energy is always conserved but can be converted from one form into another. Like when an engine burns fuel, it converts the energy stored in the fuel's chemical bonds into useful mechanical energy and then into heat, or more specifically, the melting ice cubes. Yeast breaks down maltose into glucose to produce alcohol and Co2 in the fermentation process. This is a prime example of the 1st law of thermodynamics. No form of usable energy is really lost; it only changes from one form to another</span>
