Answer:
w=2.25
Explanation:
It is necessary to determine the maximum w so that the normal stress in the AB and CD rods does not exceed the permitted normal stress.
The surface of the cross-section of the stapes was determined:
A_ab= 10 mm^2
A-cd= 15 mm^2
The maximum load is determined from the condition that the normal stresses is not higher than the permitted normal stress σ_allow.
σ_ab = F_ab/A_abσ_allow
σ_cd = F_cd/A_cdσ_allow
In the next step we will determine the static size: Picture b).
We apply the conditions of equilibrium:
∑F_x=0
∑F_y=0
∑M=0
∑M_a=0 ==> -w*6*0.5*6*0.75*F_cd*6 =0
==> F_cd = 2*w*k*N
∑F_y=0 ==> F_cd+F_ab - 6*w*0.5 ==>2*w+F_ab -6*w*0.5 =0
==> F_ab = w*k*N
Now we determine the load w
<u>Sector AB: </u>
σ_ab = F_ab/A_ab σ_allow=300 KPa
= w/10*10^-6 σ_allow=300 KPa
w_ab = 3*10^-3 kN/m
<u>Sector CD: </u>
σ_cd = F_cd/A_cd σ_allow=300 KPa
= 2*w/15*10^-6 σ_allow=300 KPa
w_cd = 2.25*10^-3 kN/m
w=min{w_ab;w_cd} ==> w=min{3*10^-3;2.25*10^-3}
==> w=2.25 * 10^-3 kN/m
<u>The solution is: </u>
w=2.25 N/m

Answer:
See explaination and attachment for the program code and output
Explanation:
#include <iostream>
using namespace std;
int main()
{
char gender; //details for gender and checking
char ans;
do
{
cout<<"Gender (M or F): ";
cin>>gender;
switch(gender)
{
case 'M':
//cout<<"Male."<<endl;
break;
case 'F':
//cout<<"Female."<<endl;
break;
default:
cout<<"Wrong Gender. Please enter again (M or F): ";
cin>>gender;
}
int Weight,Height,Age; //declaration of variables
double bmr;
cout<<"Weight: ";
cin>>Weight;
cout<<"Height (in inches): ";
cin>>Height;
cout<<"Age: ";
cin>>Age;
//bmr calculations for male and female
if (gender = 'M')
{
bmr = 66 + (6.3 * Weight) + (12.9 * Height) - (6.8 * Age);
cout<<"He needs "<<bmr<<" to maintain his weight."<<endl;
cout<<"He needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;
}
else if (gender = 'F')
{
bmr = 655 + (4.3 * Weight) + (4.7 * Height) - (4.7 *Age);
cout<<"She needs "<<bmr<<" to maintain her weight"<<endl;
cout<<"She needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;
}
cout<< "Do you want to do another one>continue (Y/N): ";
cin >> ans;
}while(ans=='y'||ans=='Y');
cout<<"\n Thanks for using my BMR calculator. Good Bye!.";
return 0;
}
