I am still unsure as to how i can relate this to Young's modulus E, shear modulus G

Homework Statement Consider a rectangular block of isotropic material of dimensions a, b and c, with c >> a or b. It is characterised by its elastic constants: Young's modulus E, shear modulus G and Poisson's ratio . The block of material is subjected to axial deformation along the c...

with the cross sectional area of the link do u just calculate it using the width between the links which is the narrowest part or should i use the area around the hole for the pin or should i treat it as a composite shape cheers NDO

Homework Statement See attachment for the problem. or visit the link http://i908.photobucket.com/albums/ac286/NDO_02/Capture.jpg Basically calculate the stress in the pin and the link in a bicycle chain. Homework Equations the average shearing stress = P/A = F/A i think the chain...

Both supports are at the same height, and i am assuming the weight of the cable and it is a distributed load here is a link to the photo http://i908.photobucket.com/albums/ac286/NDO_02/bridge.gif

Homework Statement The cable to be used for the suspension bridge can safely support a tension of 40 MN.  Calculate the shortest length of the cable that can be used to construct the bridge.  Calculate the corresponding value of h. (Neglect the issue of safety factor). L = 72...
