Final answer:
In engineering, a ramp requires a handrail on at least one side if it has a slope greater than a certain value.
Step-by-step explanation:
In engineering, a ramp is considered to have a slope greater than a certain value if it exceeds a certain angle. The maximum angle is typically determined by safety regulations and guidelines. In the case of handrails, the requirement is usually to have a handrail on at least one side of all ramps that have a slope greater than a certain angle or percentage.
For example, if the maximum allowable slope is 10 degrees, then any ramp with a slope greater than 10 degrees would require a handrail. Similarly, if the maximum allowable slope is 10%, then any ramp with a slope greater than 10% would require a handrail.
The specific value for the slope that determines the requirement for a handrail may vary depending on local building codes and regulations.
