Answer:
From the main bearings, the oil passes through feed-holes into drilled passages in the crankshaft and on to the big-end bearings of the connecting rod.
Answer:
COP_max = 18.69
Explanation:
We are given;
Heated space temperature; T_H = 26°C = 273K + 26 = 299K
Temperature at which heat is extracted; T_L = 10°C = 273 + 10 = 283K
Now the Coefficient of performance (COP) of a heat pump will be a maximum when the heat pump operates in a reversible manner. The COP of a reversible heat pump depends on the temperature limits in the cycle only and is determined by the formula;
COP_max = 1/(1 - (T_L/T_H))
Thus,
COP_max = 1/(1 - (283/299))
COP_max = 1/(1 - 0.9465)
COP_max = 1/0.0535 = 18.69
Yes it does have a large spot
Answer:
Explanation along with code and output results is provided below.
C++ Code:
#include <iostream>
using namespace std;
int main()
{
int year;
cout<<"Enter the car model year."<<endl;
cin>>year;
if (year<=1969)
{
cout<<"Few safety features."<<endl;
}
else if (year>=1970 && year<1989)
{
cout<<"Probably has seat belts."<<endl;
}
else if (year>=1990 && year<1999)
{
cout<<"Probably has antilock brakes."<<endl;
}
else if (year>=2000)
{
cout<<"Probably has airbags."<<endl;
}
return 0;
}
Explanation:
The problem was to print feature messages of a car given its model year.
If else conditions are being used incorporate the logic. The code has been tested with several inputs and got correct output results.
Output:
Enter the car model year.
1961
Few safety features.
Enter the car model year.
1975
Probably has seat belts.
Enter the car model year.
1994
Probably has antilock brakes.
Enter the car model year.
2005
Probably has airbags.
