The guard rails on suspended scaffolds manufactured after the year 2000 must be between ________, with mid-rails installed approximately halfway between the top rail and the platform surface.

The guard rails on suspended scaffolds made after 2000 must be 39 to 45 inches high with mid-rails halfway between the top rail and the platform. Such regulations are vital for ensuring worker safety.

Explanation:

The guard rails on suspended scaffolds manufactured after the year 2000 must be between 39 to 45 inches, with mid-rails installed approximately halfway between the rail and the platform surface. This safety measure is crucial for preventing falls from the scaffold.

In addition to rail height, proper tension in supporting cables is essential for scaffold stability. For example, if a uniform scaffold of length 6.0 m with varying loads is supported by two cables with uneven tensions, analyzing forces and torques would be necessary to determine the tensions required to maintain equilibrium.

The guard rails on suspended scaffolds manufactured after the year 2000 must be between 39 to 45 inches, with mid-rails installed approximately halfway between the rail and the platform surface. This ensures the safety of workers by providing a barrier to prevent falls from the scaffold.
