Question

A rigid bar, AB, is pinned at point B. Two other bars, AC and AD, are connected to point A to provide support for AB. We are investigating the behavior of this system under a specific load.

Key Details:

  • Bar properties:
    • Material: Steel with Young's modulus (Esteel) of 200 GPa and coefficient of thermal expansion (a) of 11.7 x 10^-6 /°C.
    • Cross-sectional area:
      • AC: 1960 mm²
      • AD: 1250 mm²
    • Length:
      • AC: √2 meters (square root of 2 meters)
      • AD: 1 meter
    • Inclination angles:
      • AC: θ₁ (theta 1) = 30° from horizontal
      • AD: θ₂ (theta 2) = 20° from horizontal
  • Load on bar AB: Idealized linearly increasing load with a maximum value of 30 kN/m at point B.

Problem Objectives:

  1. Determine the internal forces (axial forces) acting within bars AC and AD due to the applied load on AB.
