Hello all I was wondering if anyone could help me with the following problem. I am digging a hole in the ground that is 1.946m deep and erecting a wall. I am trying to work out whether my overturning moment of the wall is greater than the sum of all the resisting moments. Below is an image...

Hello all I was wondering if anyone could help me with the following load bearing capacity problem:- I have worked out that I have a safe soil bearing capacity of 1238kN/m^2 The area of my foundation is 5.883m^2 The total load I am applying to my foundation is 2420kg. Just based on this...

Hello all I was hoping someone could help point me in the right direction regarding the following problem. I have 2 x tanks, 1 x cylindrical and the other rectangular of a given depth H that will be installed below ground with just the top of the tank exposed as shown below:- These tanks...

Hello all I was wondering if someone could help shed some light on an equation I found regarding obtaining the slope of sewage pipes in the following paper:- The equation that is quoted to obtain the slope (equation 13) is given as:- S = 4.65 * N^2 * D^(-4/3) * (q/Q)^(-1/2) * v^2 I...

Hello all This may not sound like a civil question but I can assure you it is related to civil engineering. I am trying to export elevation data from Google Earth Pro of a town in Peru. I have obtained latitude, longitude and altitude data for the area I am interested in however I need to...

Hello all I am trying to find or work out how to calculate the Fixed End Moment (FEM) for 2 x different point loads. I have the following sketch:- All of the FEM tables I have found don't have an example where there are 2 x different point loads and I was wondering if any once could shed...

Hello all I was hoping someone could shed some light on the following question:- I have a propped cantilever beam as shown below:- https://files.engineering.com/getfile.aspx?folder=57d226be-8951-4719-8660-5cd38e42a5f3&file=Question.png I want to work out the vertical reactions at support A...

Hello all I was wondering if someone help clear up some confusion I have regarding different type of structures. Below are 4 x diagrams of beams:- https://files.engineering.com/getfile.aspx?folder=0e9e3c2d-26b2-44d8-9107-5bf3d572155d&file=Beam_Types.PNG I have seen these types before but...

Hello all I wanted to ask about beams. I have the following structure:- My question is that given this structure is composed of 2 x different EI values (the first 4m being EI and the last 8m being 2EI) then what would the purpose of using 2 different EI materials on a beam? I can only...

Hello all I was hoping someone could help with the following:- I have a pin jointed truss (all members are joined by frictionless pins and load is only applied to the joints), supported by 2 x pin jointed supports. If my pin jointed structure was loaded solely at a joint with 200kN which...

Hello all I was hoping someone could help with the following:- I have a pin jointed truss (all members are joined by frictionless pins and load is only applied to the joints), supported by 2 x pin jointed supports. If my pin jointed structure was loaded solely at a joint with 200kN which...

Hello all I was wondering if anyone could help explain how the Vertical reactions for the following structure were calculated. https://files.engineering.com/getfile.aspx?folder=f3cfa35d-9ea9-4d8a-b546-d7c1c08cd079&file=P1.png I am able to calculate the Horizontal reactions. It is the vertical...

Hello all I was wondering if any had a background or understanding on soil settlement/consolidation testing specifically oedometer testing. My understanding is that we simply measure displacement vs time however I have been given the following data:-...

Hello all Please dont shoot me down for asking this question as I know it maybe simple for most people. I am trying to remove doubt from my mind regarding the 3 x types of supports and their reactions. To me the types of support and their reaction forces are:- Fixed Support = Vertical...

Hello all I was hoping i could get some support on calculating re-action forces and creating a shear force and bending moment diagram. Some of the examples i have worked on relate to a beam supported at either end. But the example below has gotten me a little confused. I have a 21m member...

Hello all I wondering anyone could help me with the following:- When plotting a stress strain curve for a material I believe it is normal practice to express Strain in %. My question would be that when calculating Youngs modulus is it typical to use Strain in units of %? I if was to plot my...

Hi all I was wondering if anyone could help with determining whether a statement regarding compressive column testing is valid or not. 2 x Columns were loaded compressively (same dimensions, same K values), the results revealed:- Column A has a Eulers Critical Load of 83525N and a Youngs...

Hello all I was hoping someone could help me understand the Modulus of Toughness for a timber compression experiment I did. I tested a 45mm x 45mm x 45mmm timber cube under compressive load. The load was applied over a cross sectional area of 45 * 45 = 2025mm^2 My stress strain curve is...

Hello all This is a new question but it linked to a previous post. The question is, when interpreting a stress strain for compressive testing how do you know when a material has failed? I have been given a plot of 3 x compressive tests of some wooden samples. I am trying to figure out from...

Hello all I was wondering if someone could help with the following:- I am trying to understand the concept of principal stresses in terms of soil mechanics. I have a soil element that is being loaded by 25kN. I am trying to draw all of the stresses the soil element experiences. I have...
