Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

Brittle Dune Buggy Parts A mechanic who was building a lightweight dune buggy needed some high-strength aluminum parts. Since he had access to a heat-treating furnace, he decided to do the solution heat-treating and aging process himself. He obtained 2024 aluminum bars and made the parts. Then her heat treated the part in a furnace to 1200 deg F., quenched them, and allowed them to age naturally. He noticed they had small blisters over their surfaces and when he began to hammer one in place, it broke in two places. What did he do wrong? Could the parts be salvaged in any way?

Consider an AISI 1045 ferrite and pearlite microstructure. The sample is initially heated to 845 deg C and quenched in water. The samples are then tempered for 20 minutes at 316 deg c, 425 deg c, and 600 deg c. Can yu tell me what would happen to the microstructure hardness os the samples as a result of quenching, tempering theory wise.
Using the isothermal transformation diagram for a 0.45 wt% C steel alloy (Animated Figure 10.40), determine the approximate percentages of the microconstituents that form the final microstructure of a small specimen that has been subjected to the following time- temperature treatments. In each case assume that the specimen begins at 845°C (1550°F), and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure.
