durable, and efficient means of transportation across the strait. They substituted expensive materials with high-strength silicon steel, simplified the design by eliminating
The initial strength required to deform the metal The force required to deform the initial wire is: 4. Using the above graph, suppose we want to reduce a copper plate to a final thickness of 0.1 cm with at least 65000 psi tensile strength, 60000 psi yield strength and 5% elongation....

According to the mass-to-charge ratio, the molecular formula of the substance may be C6H9N2+ (M + H)+, indicating that the substance may be C6H8N2 (2,5-DMP) with one H+ removed. The results of NMR and MS analysis of the substance in the retention time of 2.69 min are shown...
12. Notably, for the third group of formulae in Eq. (24), the following cases should be considered: (1) If δ<φ, the discontinuity is “locked up” and loses its mechanical effect; thus, the strength of the rock mass is equivalent to that of intact rock. (2) If δ−φ=0 or...
We collected 5473 alloy entries with 14 alloy components, 2 processing variables, and two materials properties such as yield strength (YS) and ultimate tensile strength (UTS). X1–14 are elemental compositions for C, Si, Mn, P, S, Cu, Sn, Ni, Cr, Mo, V, Nb, Ti, and Ca. X15 and...
(2019c) proposed a formula with this coefficient to reflect the change trend and peak effect of shear stress in multi-keys. Ahmed and Aziz (2020) tested the influence of prestressing force, concrete compressive strength, presence of epoxy, and the number of shear keys. Some ways of improving...
’s regression formula, which can reduce both the cost and the time of grinding, the ideal grinding diameter can be determined [80]. In their investigation of the ideal replacement wheel diameter for internal grinding stainless steel, Tran et al. concluded that the ideal value would result in...
For image segmentation, the calculation formula of mIoU is as follows: [Math Processing Error]mIoU=1k+1∑i=0kpii∑j=0kpij+∑j=0kpji−pii. (10) The Dice coefficient is a fixed similarity measurement function that is commonly used to determine the similarity of two samples. In the ...
Metal halide perovskites of the general formula ABX3—where A is a monovalent cation such as caesium, methylammonium or formamidinium; B is divalent lead, tin or germanium; and X is a halide anion—have shown great potential as light harvesters for thin-film photovoltaics1,2,3,4,5. Among...
