The document discusses the design and analysis of a C-clamp using different materials. It analyzes the C-clamp design using both structural steel and aluminum alloy to determine the most suitable material. The analysis includes modeling the C-clamp in ANSYS, applying loads, and evaluating stresses and safety factors. The results show that structural steel performs better with higher safety factors and lower stresses under load compared to the aluminum alloy. Specifically for the handle part, the aluminum alloy shows higher stresses due to greater deflection, making structural steel preferable for withstanding the applied forces in the C-clamp.
