RE: Civil Calculations Channel

Smells like homework. Iteration is trying different values for the variables until the solution converges, i.e. the left side matches the right side. Try solving the equation with h=2.5 and you'll see the left and right won't match.

Ok thus when i will use 2.242 for only right side it should match the left side but it does not so what am i doing wrong ? Thanks for your replay

RE: Civil Calculations Channel

That's because it shouldn't match for 2.242. It should match for 3.094 (the final answer). 2.242 would be a starting point. The trick to iteration is to use whatever the newly calculated number is and try again.

For example:

Input h=2.242 you solve the right side and get 2.896 which doesn't match so on to the next iteration

Input h=2.896 repeat solving h=3.049...... repeat steps until the number entered equals the number solved. This really is basic mathematical solving, I think it's day one of numerical methods.

RE: Civil Calculations Channel

This is called successive approximation. We always hope that the iterations converge; sometimes they diverge.

Thanks i got it now it was confusing coz i thought that he/she has taken h=2.242 and that give the answer which was 3.094m. Now thanks to your post it was h=3.049 and our Hn is equal
