How to apply loads(forces and Moment) in certain positions of nodes? If i have 8 elements, no. of nodes per element=3,no. of Degree of freedom per node=9,total no of nodes=17,Total no. of degree of freedom(EL​​TSIZE)=15​3​?Attache​d a lookalikeC program

float r_matrix[ELTSIZE], x_mat[ELTSIZE];

int non_zero, i_z;

for (i = 0; i < ELTSIZE; i++)

r_matrix[i] = 0;

scanf (" %d", &non_zero);

for (i = 0; i < non_zero; i++)

{

scanf (" %d", &i_z);

scanf (" %f", &r_matrix[i_z - 1]);

}

printf ("%d %5.4f,i_z,r_matrix[i_z-1]\n\n", i_z, r_matrix[i_z - 1]);

The values of loading and their respectable positions is as follows:

3(non_zero)
