A civil engineer must design a wheelchair-accessible ramp next to a set of steps leading up to a building. The height from the ground to the top of the stairs is 2 ft. Based on ADA codes, the slope must be 1:12 or less. Slope is equal to the rise of the ramp divided by the run of the ramp.
A) Using the ADA code, what is the allowable minimum length of the ramp base?
B) Using the known height and calculated base length, what is the length of the slope of the ramp?
C) What is the ideal mechanical advantage of the ramp?D) If a person and wheelchair have a combined weight of 165 lb, how much ideal effort force is required to travel up the ramp?
