Impacto da quantidade de suportes no cálculo

2016-09-07View Original

Thread Content

A norma NB/T47003.1-2009, no ponto P128, apresenta os cálculos para 4 suportes. “Quando o número de suportes é n=4, o ângulo entre as forças que atuam sobre a placa rígida nos suportes é: θ=π/4=45°”. Se a estrutura do módulo de pesagem estiver localizada no lado direito do equipamento, e forem utilizados três suportes, será que o valor de θ continuará sendo π/3=60°? E os cálculos subsequentes, como Tr=1/2Fctg θ, também deverão ser feitos com base no valor de 60°?
