Web26 de nov. de 2024 · Curve BC. In this region of (v λ, η) space the Mohr-Coulomb failure criterion is assumed to hold:\[ \tau = \tau* + \sigma'_n tan \phi ' \] where in this equation the compressive stress σ ′ n is taken here to be positive using the conventions of soil mechanics, and where the dash denotes that pore water pressure has been taken into … WebEach day soybean planting is delayed results in about 0.5 bu/a lost yield – at a value of $2.5 to $3.00 per acre. Each day alfalfa harvest is delayed results in 5 pts RFV loss – at a value of $9.00 per acre (assuming $0.90 per pt RFV on 2-ton yield of first cutting). When put in these economic terms, the decision should be clear.
