Some national (e.g., IEEE) standards become international standards. Give one example, citing the original standard and its international counterpart.

The following are the given information of the test specimen material:   Specimen Material Specimen Width (mm) Specimen Thickness (mm) Specimen Initial Length (mm) Specimen Final Length (mm) aluminium 1.5 13.5 42.4 47.5       Grip Separation   50 mm     Total Elongation of the specimen is given by   Elongation = i-io/io x 100    l : Final length, in m l0 : Initial length, in m

What are codes and standards?

25000 bolts are going to be used to fix a certain structure. The bolts have a mean fatigue life of 10000 days with a standard deviation of 2000 days under heavy dynamic loading conditions.What is the probability that a bolt will fail between 8250 and 12500 days of use?

please solve

Can someone please help me to correctly solve all the following parts of this question. Thank you!

The following data were recorded during the tensile test of a test specimen with a diameter of 12.8 mm. The gage length is 50.8 mm. The given data are as follow; Given: Test specimen material: Aluminum Diameter of test specimen: Do = 12.8 mm Length of test specimen: Lo = 50.8 mm Force and Elongation data for test specimen Assumptions: 1. The given data is accurate and the material is isotropic 2. The direction of applied force is parallel to the length of the cylinder Requirement: To interpret and plot the stress Vs Strain curve for a given specimen DATA: LENGTH, mm STRESS, MPa LOAD, N 0 50.8 7 330 50.851 15 100 50.902 23 100 50.952 30 400 51.003 34 400 51.054 38 400 51.308 41 300 51.816 44 800 52.832 46 200 53.848 47 300 54.864 47 500 55.88 36 100 56.896 44 800 57.658 42 600 58.42 36 400 59.182 STRAIN

From the shear stress - shear strain diagram shown below, all the following are true except: Shear Stress (MPa) 500 450 400 350 300 250 200 150 100 50 0. 0.2 0.4 0.6 0.8 1.2 1.4 1.6 1.8 Shear Strain (rad) Shear Stress-Strain Curve for Brass Select one: O a. Shear stress and Shear strain are 430 MPa and 1.72 rad at fracture. O b. Shear stress and Shear strain are 250 MPa and 0.05 rad at Yielding. Oc. The elastic zone ends at a shear stress of 400 MPa and shear strain of 1 rad Od. The ultimate Shear stress and Shear strain are 430 MPa and 1.72 rad.

What is an example of experimental uncertainty?
