Explanation:
Most steels have endurance and fatigue limit about half the Tensile strength. Tensile strength of material is the limit of stress at which material then breaks. The tensile stress in a bolt is calculated through tensile force.
Answer:
#include <iostream>
using namespace std;
int main()
{
int inputNumber ;
cout << "Enter an interstate highway number:";
cin >> inputNumber ;
if(inputNumber<=0 || inputNumber >= 1000)
cout << inputNumber << " is not a valid interstate highway number" << endl ;
else{
if(inputNumber > 99){
cout << "I-"<<inputNumber<< " is auxiliary, ";
int temp = inputNumber % 100 ;
cout <<"serving I-"<<temp<<", ";
if(temp%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
else{
cout << "I-"<<inputNumber<< " is primary, ";
if(inputNumber%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
}
return 0;
}
Explanation:
- Check if input number is greater than 99, then display that the input number is auxiliary.
-
Check if remainder of input number/2 is equal to 0, then display that going east/west.
Answer:
work=281.4KJ/kg
Power=4Kw
Explanation:
Hi!
To solve follow the steps below!
1. Find the density of the air at the entrance using the equation for ideal gases
where
P=pressure=120kPa
T=20C=293k
R= 0.287 kJ/(kg*K)=
gas constant ideal for air
2.find the mass flow by finding the product between the flow rate and the density
m=(density)(flow rate)
flow rate=10L/s=0.01m^3/s
m=(1.43kg/m^3)(0.01m^3/s)=0.0143kg/s
3. Please use the equation the first law of thermodynamics that states that the energy that enters is the same as the one that must come out, we infer the following equation, note = remember that power is the product of work and mass flow
Work
w=Cp(T1-T2)
Where
Cp= specific heat for air=1.005KJ/kgK
w=work
T1=inlet temperature=20C
T2=outlet temperature=300C
w=1.005(300-20)=281.4KJ/kg
Power
W=mw
W=(0.0143)(281.4KJ/kg)=4Kw
False as there are many risk in driving
Answer:
203.0160
Explanation:
Because you add then subtract then multiply buy 7 the subtract then divide then you add that to the other numbers you got than boom
