1. combined loading
2. fatigue
3. thermal stresses
4. shock loading
shock loading
1. decreasing the cross-section area of' bar
2. increasing the cross-section area of bar
3. remain unaffected with cross-section area
4. would depend upon other factors
decreasing the cross-section area of' bar
1. to decrease length
2. to increase length
3. unaffected by length
4. other factors would decide same
to increase length
1. be independent of ratio of mass of load W to mass of bar(y)
2. increase with increase in y
3. decrease with decrease in y
4. depend on other considerations
be independent of ratio of mass of load W to mass of bar(y)
1. determining brittleness
2. protecting metal against corrosion
3. protecting metal against wear and tear
4. experimental stress analysis
experimental stress analysis
1. variation in properties of material from point to point in a member
2. pitting at points or areas at which loads on a member are applied
3. abrupt change of section
4. all of the above
all of the above
1. more
2. less
3. same
4. more or less depending on quantum of load
more
1. increases the seriousness of static loading stress concentration
2. lessens the seriousness of static loading stress concentration
3. has no effect on it
4. depends on other considerations
lessens the seriousness of static loading stress concentration
