Is the point A supposed to be the vertex? If not, the problem is unworkable and if so the picture should show a slope of 0 at A.

Thanx. for ur replies.

mmm... actually I wanted to make it as simple as possible, so I drew this figure for easy understanding of the prob.

okay! here's the link, www.youtube.com/watch?v=zVKf6hZfrhA&feature=related

just seek upto 25:24
why did he take 1/3 * 0.45fck * 0.57x
Why not 1/6 * 0.45fck * 0.57x

where, 0.45fck = 5 (in previous thread figure)
0.57x = 6 (in previous thread figure)
0.43x = 4 (in previous thread figure)


and don't worry (consider) 'b' in the youtube video, coz we are considering only area (2-D)


Now did I make the prob. clear to you guys and let me know, if I didn't .

Thanx. again.
