WebBroch and Franklin (1972) proposed a testing method called the Point Load Test. The test consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. For these tests, rock pieces must have a length at least 1.4 times their diameter (Figure 2a). The point load index, Id, is equal to
