Confusion over a retaining wall question

    Hi Deepannita,

    The formula is the area of a triangle, except that your base is a function of both the height and the force (soil weight) acting on the wall one-third up from base. Ben Norkin @ Hyperfine explains it best, but if you are not signed up on his website, you may see it here on a webinar he presented for AIA NJ.

    Towards the end, you would see it.

    Good Luck!

    Thanks! The Hyperfine video seems to suggest that only the wall is included in the height and not the footing but I encountered a question on Elif's Arequestions which gave the answer to indicate otherwise.

    You want to follow the question and understand what is requested. If the foundation is included in the drawing and dimensions are provided, or, if it is implied that you source for it within the given information, then you include it. But, If it is not shown and no reference is made to it, then it is not relevant, so, just proceed to resolve the problem with the information provided. It is important to not over think the questions. I signed up with Elif too and I see the question, I believe she added the twist to prep. us for curved balls that may show up in the exam.

    I hope this helps.

    It's really funny - I see that on March 10 someone asked the exact same question!
