you have answered 1 and 2 for me. For 3 I know the dimensions of the beam but I don't know if the placement of the strain gauges at some points on the beam matters or not.
1). Would you always go through a selection criteria to help decide on the most appropriate one to use if you had no prior knowledge of the system?
2). Would the environmental parameters need to be assessed for any kind of system regardless of the conditions?
3) Would the dimensions of...
I don't know what the formula is for working out elongation. I have looked on the web and can't find it. I tried F/AE and got 5.684x10-4. The problems come with answers and it says it should be 1.136mm but the notes on it are a bit crap so I'm just trying to arrange things to get the answer...
Just a few questions.
1). A bar of 2m and diameter 40mm, is subjected to an axial tensile force of 50KN. What will be the elongation and the reduction in diameter. The aluminium bar has a Modulus of Elasticity E = 70 Gpa and a poissons ratio v = 0.3
2). A 1.5m steel bar has a cross...
