3. A 30-cm long, 12-mm diameter carbon steel rod was
subjected to 15.5 kN of tension. Calculate (a) the stress and
strain in the rod, (b) the amount that it stretches, (c) its
change in diameter, and (d) its stiffness (k=EA/L). (e) If the
force was only 4.5 kN, by what amount would the rod have
stretched?
Q1: 1.5 in diameter steel part is quenched in oil with no agitation. (H=0.20).
If we use a 4340; 4140; 8640; 5140; 1040 steel, what would be the hardness
number at the center of the part?
1) How much stress will be generated in the 13mm diameter aluminum rod below with an increase in
temperature of 30 degress C?
- Look up the coefficient of thermal expansion and elastic modulus for aluminum (SI units) in the book.
- Calculate the temperature increase it would take for the aluminum rod to expand an contact the wall.
- Subtract that number from the temperature change given to see how much of our temperature change
will be after this contact and generate stress.
- Calculate the stress generated in that rod due to that excess temperature increase.
- Compare your answer: 13.89 MPa
