The parts of triple beam balance are identified as the following. [3]Weighing pan - The area in which an object is placed in order to be weighed.; Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs.
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [10] suspended from each arm (hence the plural name "scales " for a weighing instrument).
Planar Beam load cells; used in low profile solutions where space is limited, like medical scales and retail scales. Bending Beam load cells; used in pallet, platform and small hopper scales. Shear Beam load cells; used in low profile scale and process applications, available in capacities from 100kg up to 50t.
H-beam sections (typical column sections, due to resistance to bending in all axis) may be driven at angles "raked" to rock or other firmer soils; the H-beams are left extended above the base. A reinforced concrete plug may be placed under the water, a process known as tremie concrete placement. When the caisson is dewatered, this plug acts as ...
A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place. The movable scaffolding system is used to support a form while the concrete is cured; once the segment is complete, the scaffold and forms are moved to ...
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. A 19th-century steelyard crane
Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. [1] Cantilever construction allows overhanging structures without additional support.
A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work.
