7 black hole "facts" that aren''t true

2021-3-30 · The gravitational force due to a black hole 10 times the mass of the Sun is exactly the same as that of a 10-solar-mass star. So, an object close to a black hole will act exactly the same as if you swapped the black hole for a star of the same mass. In fact, it''s perfectly possible to orbit a black hole…

Concrete crushing based on the high-voltage pulse ...

Based on the optimal scheme of 50 mm hole diameter and 400 mm hole spacing, the influence of hole end distance and edge distance on the crushing effect of the concrete beam section was investigated. The end distance of the hole is the same as the edge distance, which has three levels of 200 mm, 250 mm and 300 mm.

Rotary Drilling

There are two groups of big rotary drilling: (1) rotary crushing by high-point loading to the rock from three cones, as shown in Fig. 7.7 a, and (2) rotary cutting by shear force from drag bits, as shown in Fig. 7.7 b. The rotary cutting can be also used to drill small boreholes in soft rocks.

Influence of Natural Aggregate Crushing Process on ...

Aggregate crushing was carried out in a Los Angeles drum, in accordance with the requirements of EN 1097-2:2020. The analysis showed that for grits of the 10–14 mm fraction, the lower values of the LA indices were obtained, which allows for obtaining a bigger index of crushing strength than in the case of crushing using the 4–8 mm fraction.
