A _________ is a sloping surface and it is adopted as a substitute for stair for easy connection between the floors.(a) Rise(b) Pitch(c) Ramp(d) StringThis question was posed to me in an international level competition.This is a very interesting question from Types of Stairs topic in portion Arches, Lintels, Stairs and Formwork of Construction & Building Materials

Answer»

The CORRECT choice is (c) Ramp

The EXPLANATION is: The usual slope of ramp is 1 in 15. But a slope of 1 in 10 is desirable. This indicates that the ramp REQUIRES more space. For instance, total length of 45 M of ramp will be required to connect the FLOOR of height of 3 m with slope and 1 in 15.
