I want to find out the area of this portion of the figure,

Here's the picture

the curve is parabolic.

welcome to pf!

hi maan143! welcome to pf!

Show us what you've tried, and where you're stuck, and then we'll know how to help!

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.

To find the area of this portion of the figure, we will need to use the mathematical concept of integration. Since the curve is parabolic, we can use the formula for the area under a parabola, which is 1/3 times the base times the height. In this case, the base would be the width of the portion of the figure and the height would be the highest point of the curve. We can also divide the portion of the figure into smaller rectangles and use the formula for the area of a rectangle (length times width) to get a more accurate estimate of the area. It's important to note that the units of measurement used for the length and width will determine the units of the final answer for the area. Overall, finding the area of this portion of the figure will require using mathematical techniques and accurately measuring the dimensions of the figure.
