Now you probably know that an accessible route has a maximum slope of 5%, or it becomes a ramp and needs handrails. So 401' - 6 1/4" converts to 401.52. Then subtract 400.14 to find the grade change of 1.38'. To find the slope, divide the grade change of 1.38' by the distance of 30' to get a slope of .046 or 4.6%, which is less than the maximum ...

The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails. The ductility of a material also plays a significant role in determining when a material ...
