Hello all I am trying to understand the forces that are acting on a pipe bend when a fluid is passing through it. I have been given the following diagram:- The bit i cannot get my head around is why does P2A2 point the way it does i.e. down towards the left shouldn't is point the opposite...

Hi Lnewqban If i can ask a follow on question which is this, if i had the same example but this time i added a pump half way along the pipe then would the gain in energy from the pipe be described in Bernoullis equation as:- This equation makes sense to me because I interpret this equation as...

Thank you.

Hello community I have been trying to get my head around Bernoulli's equation when factoring in energy loss due to friction. I am trying to understand the concepts and i was hoping someone could remove some doubt from my mind by confirming the following:- 1) Would the following statement be...

Berkeman If an exponential/log function would meet Day 1 = 100kg and Day 112 = 67kg then i would be happy to try that but i just don't know how to generate the function that meets those requirements.

Hi mfb Would some form of logarithmic function work?

Hello all I was hoping someone can help with the following problem. I am trying to create a parabolic formula to give me target weight. For example:- Day 1 = Target Weight 100kg Day 112 = Target Weight 67kg Each day is consecutive - can anyone help me to create a parabolic formula that goes...

Hi All I was wondering if there was a quick method of calculating the Second Moment Of Area about the Z axis shown below? I can quickly work out the Second Moment Of Area about the Y axis but the Z axis is proving very difficult and time consuming as the parallel axis therom needs to be...

Hi Archaic That has cleared up a lot of things for me thank you, If i may ask some final question just to clear up my doubt which are:- 1) Force can be defined as Mass * Acceleration which is the same thing as saying Force is equal to change of momentum with respect to time, which is the same...

Hi ehild Thank you for your response, to be honest i don't think i fully understand. I re-wrote velocity out to get:- But this is as far as i get. I tried to re-write acceleration (as you have shown) which gets me to:- From set 7, i have Force = Mass * derivative of velocity with respect...

Hello everyone I was hoping someone could shed some light on the following:- I am trying to derive the equation of Momentum from Newton's 2nd Law. What I know is the following:- I don't know how to get from Force = Mass * Acceleration TO Momentum = Mass * Velocity. I have attempted to...

Thank you all. I think i am going to start with solid works to being with and at the same time continue to learn the basics. I have now started by adventure into the FEA :) Thank you.

Hello all I was wondering if anyone could figure out the what the equation below means, specifically the W term? The equation to calculate bending stress for a cross section that i have used and i know is correct is:- Bending Stress = Moment (M) * Distance From Neutral Axis (Z) / Second...

FEAAnalyst. Thanks Just out of interest what FEA software do you use? I wanted to start using one but wasnt sure which one would be the easiest to learn just as a starter. A few people are using Solidworks. Thoughts? Thanks

Hello all I am trying to calculate the bending stress of a simply supported beam with a load of 12kn at the middle of a 6m span, member depth of 0.016m I have drawn both the bending moment and shear force diagram. I want to know the following:- 1) When calculating the bending stress would...
