The beam is supported by two rods $A B$ and $C D$ that have cross-sectional areas of $12 \mathrm{mm}^{2}$ and $8 \mathrm{mm}^{2}$, respectively. Determine the position $d$ of the $6-\mathrm{kN}$ load so that the average normal stress in each rod is the same.

Key Concepts

Axial Stress

Axial stress is the internal force per unit cross-sectional area acting along the length of a structural member. It is calculated by dividing the applied force by the cross-sectional area, providing a measure of the intensity of the tensile or compressive force in the member.

Cross-sectional Area

The cross-sectional area of a structural member plays a critical role in determining how much stress the member experiences under a given load. A larger area distributes the load more widely, resulting in lower stress, while a smaller area concentrates the force, leading to higher stress.

Load Distribution

Load distribution refers to the method by which an applied external load is shared among different structural members. In systems with multiple load paths, ensuring that the load is distributed in a way that equalizes the stress across members (or meets design requirements) is essential for maintaining structural integrity.

Force Equilibrium

Force equilibrium is a fundamental principle in statics where the sum of all forces and moments acting on a system must equal zero. This principle is used to determine how forces, such as those in different members of a structure, balance each other to maintain a stable configuration.
