A drop structure, also known as a grade control, sill, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam's spillway, to pass water to a lower elevation while controlling the energy and velocity of the water as it passes over. Unlike most dams, drop structures are usually not built for water ...
A plan and side view of a generic, empty canal lock. A lock chamber separated from the rest of the canal by an upper pair and a lower pair of mitre gates.The gates in each pair close against each other at an 18° angle to approximate an arch against the water pressure on the "upstream" side of the gates when the water level on the "downstream" side is lower.
A silo (from Ancient Greek σιρός (sirós) 'pit for holding grain') is a structure for storing bulk materials. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.
Timber sills can span gaps in a foundation. A sill plate or sole plate in construction and architecture is the bottom horizontal member of a wall or building to which vertical members are attached. The word "plate" is typically omitted in America and carpenters speak simply of the "sill". Other names are rat sill, ground plate, ground sill ...
If the service core (which contains the elevator shafts) becomes too big, it can reduce the profitability of the building. Architects must therefore balance the value gained by adding height against the value lost to the expanding service core. [10] Many tall buildings use elevators in a non-standard configuration to reduce their footprint.
Description. Space elevator structural diagram--corrected for scale+CM+etc.svg. English: This file is an update of en:File:Space_elevator_structural_diagram--corrected_for_scale+CM+etc--regenerated_as_SVG.svg. It modified that file by 1) regenerating it as an .SVG. And, 2) clarifying that the cable rotates with the Earth and remains vertical.
Elevator. Outside of typical elevators, shown in an office building in Portland, Oregon. This elevator to the Alexanderplatz U-Bahn station in Berlin is built with glass walls and doors, exposing the inner workings. An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between ...
Sill (geology) Illustration showing the difference between a dike and a sill. In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A sill is a concordant intrusive sheet, meaning that it does not cut ...
