When it comes to understanding how your engine is performing, torque and power are key data points to assess. Torque is an effective measurement when seeking to quantify the true mechanical torque on the driveline component, such as a driveshaft or a coupling. The...
Engineering Dynamics Incorporated (EDI) was requested to help perform an axial load test on a vertical water pump. Since commissioning, the pump experienced accelerated bearing and shaft wear. There was concern that problems might be due to up-thrust resulting in a...
The Park Street Bridge in Alameda County, California is a four-lane double-leaf bascule (draw) bridge spanning 372 feet across the Oakland Tidal Canal between the Cities of Alameda and Oakland. When rework construction modified the weight of the original lift spans...
Houghton Lift Bridge, Houghton, MI – Mechanical rework and painting of the double deck, vertical lift bridge at Houghton, MI had potentially changed the weight of the movable span. Lunda Construction, the primary contractor, was required by the Michigan D.O.T. to...
A civil engineering company in Chicago was hired to determine the start-up torque for a column pump at a water treatment plant for the City. The City desired to upgrade the pump drive system by employing reduced voltage starters to minimize in-rush current. Some of...
