In Alberta, ramps that are designed for people using mobility devices must meet certain safety requirements. One such requirement is that the angle between the ramp and the horizontal must be less than 4.8 degrees. Explain whether or not the ramp in the picture below is acceptable.
The ramp has a 94.7 degree angle but I'm not sure if there are other calculations I need to do.
No picture. Ramp of 97.4 degrees is almost right angle. Typo?
To determine whether the ramp in the picture is acceptable according to the safety requirement of having an angle less than 4.8 degrees, we need to perform some calculations.
The angle between the ramp and the horizontal is given as 94.7 degrees. However, to compare this angle to the specified requirement, we need to subtract it from 90 degrees (since a perfectly horizontal surface would have a 90-degree angle).
90 degrees - 94.7 degrees = -4.7 degrees
From the calculation, we can see that the result is negative (-4.7 degrees). In this context, negative angles don't make sense. Angles are typically measured as positive values.
Since the calculated angle is negative, it implies that the ramp in the picture actually slopes downward, rather than upward as intended. Therefore, based on this calculation, the ramp is not acceptable according to the safety requirement.
However, it is important to note that visual inspection alone might not be sufficient to determine the angle accurately. To get an accurate measurement, you may need to use an angle measuring tool or consult the specific measurements and specifications of the ramp provided by its manufacturer.
