We assume that the rock volume that is fragmented and thrown is a triangular prism and its cross section is a triangle with a height of B and a width of S, where B and S are burden and spacing, respectively. Thus, the rock volume blasted by an inclined borehole is approximately equal...

directly in the test is the sum of the cantilever vertical deflection and the average of two to three measured displacements at load P in conventional nanoindentation tests that were conducted within the (FIB-affected) region of the bulk fused quartz prism close to the fixed end of each ...
1) irregular triangular prism 非等腰三棱镜1. This article introduces a new method of measuring the glass refractivity of a prism with a cross section in the shape of irregular triangle,namely measuring the glass refractivity of an irregular triangular prism with the method of vertical light ...
FIG. 2 is an oblique view of a triangular prism unit which constitutes the toy of the present invention. FIG. 3 is an oblique view showing another plane of the triangular prism. FIG. 4 is a partial vertical cross section to show the structure of the part of a unit to be connected...
An oriented circular light-reflecting plate with triangular micro prisms having identical cross sections and a circular plate lamp made therefrom, wherein a plurality of annular micro prism bodies (111) are arranged on the prism surface (11) of the light-reflecting plate (1), the cross sections...
The top and sides of the box are flat, the bottom has a ridge so that the emerging beam has a triangular cross-section. ADVANTAGE - Simple and inexpensive design giving both main beam and dipped beam functions.ERNST HANS-OTTO DRPEITZ WOLFGANG...
The exact solution of Saint–Venant's problem of torsion of a prism with triangular cross-section is extended from the case when the latter is equilateral to a two-parameter family including isosceles and irregular triangles, but not covering all such shapes. The solution is based on a stress...
The vertical supports (1) contain at least one prism-shaped space (5) in the support surface region which has a substantially triangular cross-section. This space includes a lower resting surface which slopes upwards from the outer wall of the support to the support surface (51) on the ...
