URGENT!!!
1 answer:
The amount of NOx emission produced by a household is required.
The total amount of NOx the household is responsible for is 91.06 kg.
1 car produces 11 kg of NOx per year.
Natural gas burning produces 4.3 g of NOx per therm.
Electric power plant produces 7.1 g of NOx per kwh.
2 cars will produce of NOx.
1200 therms of natural gas will produce
9000 kWh will produce
Converting all to kg and finding the total amount
The total amount of NOx the household is responsible for is 91.06 kg.

Answer:
(a) Elongation of the rod==5.61×10⁻⁹m
(b) Change in diameter=1.640×10⁻⁸m
Explanation:
Given data
Diameter d=78 in=1.9812 m
Cross Area is:
Applied Load P=17 KN=17×10³N
E=29 × 106 psi=1.99947961×10¹¹Pa
Stress and Strain in x direction
Stress in x direction
σ=P/A
σ=5517.25 Pa
Strain in x direction
ε=σ/E
ε=2.76×10⁻⁸
Part (a)
Elongation of the rod=Lε
=(0.2032)(2.76×10⁻⁸)
Elongation of the rod==5.61×10⁻⁹m
Part(b) Change in diameter
Strain in y direction
ε₁= -vε
ε₁= -(0.30)(2.76×10⁻⁸)
ε₁=-8.28×10⁻⁹
Change in diameter=d×ε₁
Change in diameter=(1.9812m)×(-8.28×10⁻⁹)
Change in diameter=1.640×10⁻⁸m
