Civil Engineering Academy presents a useful video tutorial that provides great benefit to the student who will appear in Civil PE Exam. This construction video is based on how to obtain the load distance of a crane across a building.
A crane having a 80' book is applied to provide a load over a building. In this video point X denotes the nearest position of boom toward the building.
Now the question is that what will be the extreme distance that the load contains from the edge of the building if the boom is totally expanded (feet)?
