this is just a discussion board question that i need to answer.
I’d like to know what you think of the “wrecking ball” which David Hume applies to science. Does he really show that the “necessary connections” which we commonly refer to as the “Laws of Nature” are merely based on psychological conditioning– or, as he puts it, “constant conjunctions” of similar events? What do you think is– or should be– the impact of Hume and empiricism in this era of great scientific and technological advances?
5. (3.5) Determine the maximum pressure that a cylindrical gas reservoir can withstand, using the three flow criteria. Use the following
information:
Material: AISI 304 stainless steel – hot finished and annealed,
Thickness: 25 mm
Diameter: 500 mm
Length: 1 mm
Hint: Determine the longitudinal and circumferential (hoop) stresses
by the method of sections. (Tresca: 20.5 MPa, von Mises: 23.67 Mpa)
6. (3.9) The stress-strain curve of a 70-30 brass is described by the equation:
Until the onset of plastic instability.
(a) Find the 0.2% offset yield stress. (68.2 MPa) (b) Applying Considere’s criterion, find the real and engineering stress
at the onset of necking. ( )
