The statement is true because using one thick shim can provide a more stable and secure adjustment compared to several thin shims stacked together. A single thick shim minimizes the risk of uneven loading and potential movement between layers, which can occur with multiple thin shims. This is particularly important in applications where precision is critical, as uneven distribution can lead to mechanical failure or misalignment over time.

In addition, a thick shim often has a greater surface area, allowing for better distribution of forces and reducing stress concentrations in the materials being supported. It simplifies the installation process and reduces complexity, which can be advantageous in both construction and maintenance.

In many scenarios where load-bearing surfaces must be aligned accurately and securely, a single robust shim is typically preferred to ensure that the structural integrity is maintained, thus providing a more dependable solution.
