Guardrails must be capable of withstanding a downward and outward force at the top edge of how many pounds?

Explanation:
Guardrails are designed to stay sturdy where people lean or push against them, especially at the top edge where force is concentrated. The standard requires the top edge to withstand a 200-pound load applied downward or outward without failing. This amount reflects safety codes that aim to protect workers from rail deformation or collapse during typical leaning or pushing scenarios, keeping the protected area secure. A lower force like 100 pounds wouldn’t meet the safety requirement, while higher forces such as 300 or 400 pounds exceed what the standard calls for in regular use. So the value used is 200 pounds.
