Problem 7.115

The steel pressure tank shown has a 750-mm inner diameter anda 9-mm wall thickness. Knowing that the butt-welded seams forman angle b 5 508 with the longitudinal axis of the tank and thatthe gage pressure in the tank is 1.5 MPa, determine, (a) the normalstress perpendicular to the weld, (b) the shearing stress parallel tothe weld.

Step 1 of 3

Reductive Materialism  Mental states= neural states o Pain= c-fiber firing  Benefits of Reductive materialism o No interaction problems o No problem of other minds o Flaws: not obvious ones  Arguments o Parsimony  Either pain is perfectly correlated with brain processes, or it is identical to brain processes  Occam’s razor  Therefore pain is identical to certain brain processes o Causal role  Pain= the occupant of causal role R  Neural state N occupies causal role R  Therefore pain= neural state N  Objections o Illiteracy/Unknowing  I know about my pain, I don’t know about c fibers therefore they are not equal (Leibniz’s Law) o Possibility  Its possible that lighting will not turn out to be atmospheric electrical discharge, but that doesn’t completely rule it out o
