The weight a 4-inch thick sidewalk can hold depends on several factors, including the type of material used (e.g., concrete, asphalt), the quality of the installation, and the soil conditions beneath it. Generally, a properly constructed 4-inch concrete sidewalk can support pedestrian traffic and light vehicles, typically up to about 5,000 pounds per square foot. However, for heavier loads, it's advisable to consult local building codes or a structural engineer for specific guidelines.

One advantage of using a frame structure as a helmet is that it can provide strong support and protection due to its rigid design. Another advantage is that frame structures can be lightweight, which can reduce strain on the wearer's neck and head.

As a general reference, 1/8" thick plexiglass can typically hold up to 15 pounds per square foot, while 1/4" thick plexiglass can hold around 60 pounds per square foot. For greater load-bearing capacities, thicker plexiglass sheets or additional support structures may be needed.
