MET313: Applied Strength of MaterialsThere are 6 practice problems in this assignment.Looking Back to Week-1 Practice Problem 1May need to be redrawn!The above figure shows two circular rods carrying a casting weighing 11.2 kN.If each rod is 12.0 mm in diameter and the two rods share the load equally,compute the stress in the rods.
Let’s solve the above problem with a different load and rod diameter combination as given below;Looking Back to Week-1 Practice Problem 2CasesLoad(kN)Rod Diameter(mm)Normal Stress MPaGuided Practice1010XX111012XX221812XX331818XX4Looking back to Week-1241567.91MPA
May need to be redrawn!Theabove figure shows an axial tensile force of 10 000 lbs applied to an aluminum bar that has adiameter of 0.75 in. Before the load was applied, the length of the bar was 10.000 in. After the loadis applied the length is 10.023 in. Thus, the total deformation is 0.023 in.Strain, also called unit deformation, is found by dividing the total deformation by the original lengthof the bar. The lowercase Greek letter epsilon () is used to denote strain:Definition of StrainFor the case shown in the above figure;
