Dear K.K Sir, please also discuss the detail for how to find out maximum pull out load applied to rock bolts at site during put out test.

[@ErKaushalKishorSingh]

Dear Mr. Pawan,
Formulas fo calculating the ultimate/maximum bond strength/ pull out load has been given in video ,please see carefully

[@pawangupta6343]

@@ErKaushalKishorSingh Dear Sir, in the video you are discussing about the formula for calculating Bond strength after applying the load to rock bolt (i.e. after getting the value of " W " from site).
Sir, their is not any other method of calculating the maximum pull out load required to apply the rock bolt at site to test the pull out of rockbolt
