to decrease length
to increase length
unaffected by length
other factors would decide same
be independent of ratio of mass of load W to mass of bar (y)
increase with increase in y
decrease with decrease in y
depend on other considerations
determining brittleness
protecting metal against corrosion
protecting metal against wear and tear
experimental stress analysis
variation in properties of material from point to point in a member
pitting at′points or areas at which loads on a member are applied
abrupt change of section
all of the above
more
less
same
more or less depending on quantum of load
