A machine element's strength depends on:
Because different materials have different strength, for example, same element made up of mild steel and cast iron shall have different strengths.
Heat treatment of material affects mechanical and physical properties of material. Annealed steel and hardened steel have different strengths.

For the multiple choice, please check all that apply The factor-endowment theory predicts that because the United States is relatively abundant in capital and relatively scarce in labor, it will export capital-intensive goods, and its import-competing goods will be labor intensive. In the 1950s, Wassily Leontief, a Russian-American economist, tested this proposition by analyzing the capital/labor ratios of export industries and import-competing industries, using U.S. data. He found that the capital/labor ratio for U.S. export industries was lower than that...
Select the statements that apply to hemolytic disease of the newborn. Check all that apply. Check All That Apply This occurs due to Rh incompatibility between an Rh+ mom and Rh- baby. Fetal RBC leakage sensitizes the mother to make anti-Rh antibodies. Anti-Rh antibodies that are lgG can cross the placenta and induce complement-mediated lysis of fetal RBCs. After sensitization with Rh+ fetal RBCs, all subsequent pregnancies (Rh+ and Rh- fetuses) are at risk for hemolytic disease. Hemolytic disease is...
