What is the tolerance zone (and Material Boundary) for a non-cylindrical feature such as a slot or groove?

Identify the timing limits for both the minor and major loads for the Rockwell procedure, including the relevant ASTM code section. Why is timing so important to the Rockwell procedure ?

In a thin-walled cylindrical pressure vessel, the axial and circumferential joint efficiencies specified to account for fabrication process and inspection procedure considerations are 1.0 and 0.5 respectively. The ratio between the circumferential stress and axial stress used in the design is, O a. 4:1 O b. 1:1 Oc. 2:1 O d. 1:2

How can the strains that act for some other orientation be determined?

What exactly is involved in the length property?

A reciprocating type ball-on-disc tribometer was used to measure the tribological behaviour of the thermally sprayed cobalt oxide coatings against the alumina (Ø 6.35 mm) counterface. After wear testing at high temperatures, the area of the wear tracks was 300 μm² measured by a white light microscope. The following parameters were used for sliding wear testing. Parameters Applied load (N) Sliding velocity (cm/s) Test frequency (Hz) Track length (mm) Total sliding cycles Total sliding distance (m) Values 10 3.14 1 10 2500 50 Determine the wear volume in mm³ that was removed during the sliding process and the specific wear rate (mm³/N.m.).
