Axial loading involves applying a force along the length of a structural element, which can lead to deflection. To analyze axial loading, it's essential to determine the maximum weight (W) and the reactions at supports. Calculating the force in each rod is crucial for understanding the system's behavior under load. Knowledge of material properties, particularly the modulus of elasticity (E), is necessary for solving deflection issues. Understanding these concepts is vital for accurately addressing axial loading scenarios.
