    Study Notes

    Shaft Overview

    • A shaft is a metallic component designed to rotate or oscillate continuously.
    • Its primary function is to transfer movements or torque within a machine.
    • Shafts connect various machine components separated by distance, allowing for relative motion between these parts.

    Beam Selection Methodology

    • Begin by identifying the Dead Load (DL) and Live Load (LL) to assess the structural requirements.
    • Calculate the Ultimate Force (PU) after determining the DL and LL.
    • Proper beam sizing is critical for functionality and cost-efficiency:
      • A beam that is too thin may buckle under the applied load.
      • Using a beam that is excessively thick can lead to unnecessary expenses.
