How it Works: Engineering Bridges to Handle Stress

17/3/2017· Environmental sources of stress include: Tides, waves, and water back-ups. Water is one of the most powerful forces on earth. Engineers often insert openings into bridge abutments to allow water to flow through rather than push against them. Winds. Large gusts of wind can cause bridges to sway and twist. Modern ones are lighter and more aerodynamic, allowing …

Monitoring Soil Moisture for Optimal Crop Growth – Help Desk

Water Holding Capacity. Among other things, soil is a storage medium for farm water until it is used by plants. Water resides in the spaces between soil particles. The force of gravity constantly acts on water in the soil to move it downward and out of reach of plants. The counterbalancing force which keeps it from moving downward is surface tension, which causes the water to …

Stress Relief of Steels :: Total Materia Article

Stress relieving is applied to both ferrous and non-ferrous alloys. Carbon steels may be stress relieved by holding a temperature at 1100 to 1250°F (600 to 675°C) for 1 hour per inch (25 mm) of thickness. Stress relieving offers several benefits. For example, when a component with high residual stresses is machined, the material tends to move
