Principles of Mechanical Design

  1. The man has a weight 𝑊 stands at the center of the plank. If the planes at 𝐴 and 𝐵 are smooth,
    determine the tension in the chord in terms of 𝑊 and 𝜃.
  2. Determine the component reactions at fixed support 𝐴. The 400 N, 500 N, and 600 N forces are parallel
    to 𝑥, 𝑦, and 𝑧-axes respectively
