If in two right triangles, the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent. 1. PL is an altitude from P ofΔPQRon QR such that QL = LR. Then, ...
Flow-induced vibrationEqual-diameter cylindersLattice boltzmann flux solverImmersed boundary methodTo explore the relationship between dynamic characteristics and wake patterns, numerical simulations were conducted on three equal-diameter cylinders arranged in an equilateral triangle. The simulations varied reduced...
To solve the problem, we need to apply the triangle inequality theorem, which states that in any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. Let's denote the sides of triangle ABC as
