I don't know it may but i always thought shear stress was present in all compoenets and in fact in a tenisle stress test the test specimen did not actually fail in tensile stress but in shear stress. I may be looking to far into the question can the tensile stress i have calculated also be the...

Homework Statement Hi i have the following question a component of 200mm2 cross sectional area is subject to a tensile force of 40kn Determine the tensile stress and the maximum shear stress that exist within the component ? I can work out the shear but how can i work out the maximum Shear ...

Thanks for all the help i solved it in the end Many thanks

I have solved that problem now calculating poissons ratio having difficulty transposing the formula to find v

I think i am doing something wrong i calculated G which i feel is right with other collegues of mine but am i right in saying E = stress / strain then i get a value of V = .765 which can not be right

yes i do know what it is but the formual has two unknown values in it poisson's ratio and E. I also know that i have to calculate poissons ratio next and i know this is equal to lateral strain / longditudinal strain. But i don't know how to get these values from the question Regards

what is 4.22 x 10 -7 measured in and what forumula do i use next Regards

The answer i get is very small 4.22 x10-7 Is my working out right 7 x 0.32/ (0.045to the power 4 x pi / 32) x 2

Am i correct in saying that M is the bending moment and in this case it is = to 500 Newtons

i take it that i re-arrange the formula to get G am I correct Regards

My first thoughts on the question were to figure out v then with v= lateral strain/longditudinal strain i can only figure out one of these strains i then got stuck as v is in the other formula. Apoint in the right direction would be helpful Regards

Homework Statement A shaft of 0.3 metres long and 45mm diameter twists 2 degrees under a torque of 7kNm. On a tensile test the same material extends 0.015mm on a length of 110mm. If the tensile force producing this extension was 500N and the diameter of the test piece was 5mm determine the...
