Deadweight testers are used as a for accurate measurement to calibrate pressure gauges‚ transmitters‚ transducers‚ recorders and controllers. Deadweight testers are very accurate‚ they produce pressure by applying force using calibrated stainless steel or brass weights over a predetermined area. There are numerous models available to meet specific applications. A typical deadweight tester consists self-contained pump for the generation of pressure‚ they also include a piston‚ cylinder‚ table‚ weights

than half of the bridges that were made‚ were made out of stone. But since the United States had so much wood‚ they made a lot of wooden bridges in those times and a vast majority of them were truss bridges. As the years passed on‚ the real iron and steel organizations are gone‚ truss bridges stay as their legacy. One of the most famous truss bridges is the Tokyo Gate Bridge in Japan. There is a variety of truss bridges‚ like the Pegram truss‚ Howe truss‚ and the Long truss. The Pegram truss has wires

Another advantage of copper is that it can be recycled without any loss of quality. As pure copper is too soft for structural elements or most practical appliances‚ it needs to be hardened and strengthened. It is therefore combined with

There are four structural levels of the body. Cells‚ tissues‚ organs and organ system. Cells are the basic structure and make up tissues. Two or more tissues make up the organs and the organ system are 2 or more organs that function together.
