PLATE GIRDER BRIDGES

Plate girders became popular in the late 1800’s, when they were used in construction of railroad bridges. The plates were joined together using angles and rivets to obtain plate girders of desired size. By 1950’s welded plate girders replaced riveted ...

REYNOLDS EXPERIMENT

OBJECTIVE: To perform the Reynolds experiment for determination of different regimes of flow. BASICS: The flow of real fluids can basically occur under two very different regimes namely laminar and turbulent flow. The laminar flow is characterized by fluid particles moving in the ...
