In the article the construction of new pnevmomechanical seedmeter is offered with the peripheral location of cells for the exact sowing of seed of the cultivated cultures. Dependence of moving of seed is got on a shoulder- blade from the corner of rotation of disk, the chart of dependence is built. The border value of angulator of rotation of sowing disk is found for the assured going down of superfluous...
Were considered different types of the composite beams for construction of the wooden frame houses as well as were offered new construction combination of composite Ibeam
Study of technical and economic possibilities of mechanization installation process for the construction of steel silos of galvanized steel by rearing revealed a more efficient scheme. For these schemes investigated as severity and intensity of workers. That allowed us to estimate the severity and category of labor as one of the energy efficiency of the technical process considered.
The article presents an analysis of the properties of tractrix curve, substantiates the expediency of using it as the forming curved surface of the press head working channel of plant materials in order to reduce the energy intensity of the materials pressing process. A method of constructing a tractrix is described and factors affecting the design parameters of the forming head with the curved working...
Приведено аналитическое описание кривых в полярной системе координат, отвечающих заданным свойствам механического (постоянство крутящего момента, создаваемого силой постоянной величины нажатия стержня вдоль нормали на кулачок, очерченный искомой кривой) и геометрического характера (постоянство угла пересечения заданной кривой с искомой при вращении последней вокруг полюса).
