Hi nvn, Sorry for the late reply to your post, I was made redundant and only recently found a new job! I agree entirely with what you said and understand exactly where I've gone wrong and how you and Studiot were correct. Thanks again for all your help. Jus.

nvn...this is an interesting point. I did think of this when I was going through the calculation again. Should the deformation be '-'ve instead of '+'ve because it is a contraction rather than an expansion? I agree, this is a definite possibility. But what I don't understand is why the...

Guys, thanks so much for your help on this. Studiot, I was actually practising the method laid out in the chapter I am going through at the moment which isn't actually using the energy method - I haven't revised that chapter yet. But thanks for conforming the answer of 1600N. What was...

Hi nvn, Please accept my apologies if I have been over-persistant with the question. It's not a quick thing to calculate and I appreciate that you have a lot of other work to do...sorry for mithering. I get the exact same answer as you when I change the direction of the force on Fde...

Hi nvn, It's an interesting point that you've made. I did notice this myself and I think that you are right, Fde should be pointing the other way in the free body diagram. But this is where I'm getting confused - surely it wouldn't matter which way the forces point in the first place as...

Hi there, The first thing I wanted to say (as I said the last time I created a new thread) is that this is NOT A HOMEWORK QUESTION! From the rules laid out, it says that homework for undergraduates and college students should go in the homework section. I have a degree in Mechanical...

Hi Studiot, Thanks you for yur help on this. I have sent you a message with some details about what I am looking for. Thanks again for your help. Kind Regards, Jus

Yes thank you very much for that, I might have to ask for your help again very soon Studiot. On a completely different topic, do you recommend an particular book to purchase on the topic of materials / soild mechanics? I have to say that this Benham one is quite tough to follow. It was on...

Yes F would be the vertical component of \sigma1 x Area. Thanks again for all your help on this. Kind Regards, Jus

Studiot, you are a legend! I fully understand the process that has been adopted here. I just couldn't visualise what the equation was saying. Just to make sure I have this clear in my head for the first party of the equation, please could you have a look at my attachment and just confirm...

Hi Studiot, Thank you so much for replying. I've actually been going through the whole book again, page by page, refreshing my memory from my university days so I should hopefully be ok with membrane theory. I do understand the overall process of what we're trying to achieve, it's just...

Hi there, I could really do with some help with this. First of all, this is NOT a homework question. It is a question that is listed in Benham & Crawford’s 'Mechanics of Engineering Materials' book. I am just reading through my books again and I'm stuck on this problem. As the book is...

Hi Samson07, I think this needs to be tackled from a strain perspective as well as a stress perspective as the material is a laminate. For composites, you need to perform both on-axis properties and off-axis properties in order to fully analyse the laminate. Try looking under 'Stress and...

Hi Wingman5, The first thing that you need to be aware of is that Engineering (which ever one you do generally) contains a LOT of maths. I studied Mechanical Engineering at university and have been working as an Engineer (currently designing pressure vessels) for over 10 years. The level...

Hi nameVoid, I use 'Engineering Mathematics' and 'Advanced Engineering Mathematics' by K.A. Stroud. The advanced book gives some pretty good explanations of advanced Calculus including Gradients, Divergence & Curls of Vectors. Not too sure if the above is of help. Hope so though...
