best course for beginner on youtube...
Hello sir! Your videos have been really helpful and I just wanted to thank you. Please is there a video about a box culvert??
just wondering why the radius is 9mm instead of 8mm
The diameter of the bolt is 16cm so the diameter of the holes is (16+2)=18cm
18mm*@@UB-us3ti
