How to determine the uniaxial tensile strength of rock?

The shape and test method of the sample are shown in Figure 1. When the tensile force p is pulled off on the test machine, the tensile strength of the rock is:
σ=10p/A, MPa
The initial cross-sectional area of ​​the A-rock break section, cm 2 .
