Question:
Suppose rock bolt load is 16,400 pounds and bolts are spaced on 5 ft centers in a square pattern. Find the bolting “pressure” pb. What layer thickness is this bolting pressure equivalent to assuming a single layer roof beam sagging under self-weight alone with simply supported ends. Note: Specific weight of the roof layer is approximately 158pcf.

I was employed studypool for the first time in tutoring. I did well since most of my students and clients got the necessary information and knowledge requested for. I always submitted the answers in time and followed the correct formatting in answering eg MLA or APA format,
Again I worked with the writers bay where I did writing and got many clients whom we worked with so closely. They enjoyed every single service I delivered to them. My answers are always correct.
