Tensile Definition and 160 Threads

Homework Statement "The axial load for a given test sample carries 1590 N. Calculate tensile stress at sections (1) and (2) assuming the sample thickness is 5mm. (Rectangular cross section). http://img208.imageshack.us/img208/121/tensilestressby1.th.jpg Homework Equations normal...

Why would a rope have a lower bending and compressive stiffness that a rod of the same diameter, but would have the same axial tensile stiffness?

Hi, I am doing a small project on the "construction and control of a modern tensile testing machine" and am a bit unsure as to where to start on this! Does anyone have any ideas as to where I could find information on this subject, or know anything that might be helpful? Thanks, Chris

I am a Physics novice. While reading an article on tensile strength in wikipedia, I began to wonder what force is responsible for keeping the atoms or molecules of something like a rope together. I mean what force would tension on the rope would have to overcome in order to break the rope...

Max tensile strength of "Unobtanium" "Unobtanium", of course, is that ever popular fictional material used in Sci-Fi to do things that today's materials can't. The idea being that although the materials we know of and use today have well established limits, there's no telling what will be...

How is tranverse tensile strength defined? How is it measured for thin fibers? Some high strength fibers such as carbon fibers have longitudinal tensile strength of 1,000,000 psi. But these fibers have diameters that measure in the microns. How could a transverse tensile strength be measured in...

Could anybody tell me what material will give the best tensile strength to weight ratio? I figure it's between steel cable and the nylon type stuff used in some dog leashes, but I'm not sure which.

Hi All, I have been working on a product development project and have run into a snag that I was hoping I could get some advice on. We need to determine the mechanical properties of a thin-walled nickel tube. Specifically young's modulus and yield strength. The current wall thickness...

A 1260kg freight elevator is supported by a steel cable of diameter 34.9mm. It is loaded with a crowd of people collectively having a mass of 2850kg and it is descending. a) What is the strain on the cable while the elevator is descending at the constant speed of 2.30 m/s? b) What is the...

Having a bit of a problem with this question, Find the minimum diameter of an alloy cable, tensile strength 75 MPa, needed to support a load of 15 kN. I know the answer is 1.6cm but i need someone to help explain how to get it. Ive got this far... Tensile strength of cable = 75 MPa...
