An axial load P is applied to the 32-mm-square aluminum bar BCas shown. When P 5 24 kN, the horizontal deflection at end C is4 mm. Using E 5 70 GPa, determine (a) the eccentricity e of theload, (b) the maximum stress in the bar.

Thermodynamics I Lecture notes System: the object/ volume Closed system- A fixed quantity of matter. Control Volume- A fixed volume of space. Isolated System- Nothing crosses boundary. Property- A macroscopic quantity that can be assigned a value at any point in time without any knowledge of the history of the system. State- Condition of a system as described by the value of its properties. Thermodynamics process- A change in state. Steady State- The state of a system is unchanging in time.
