Bed load

The term bed load or bedload describes particles in a flowing fluid (usually water) that are transported along the bed. Bed load is complementary to suspended load and wash load.

Bed load moves by rolling, sliding, and/or saltating (hopping).

Generally, bed load downstream will be smaller and more rounded than bed load upstream (a process known as downstream fining). This is due in part to attrition and abrasion which results from the stones colliding with each other and against the river channel, thus removing the rough texture (rounding) and reducing the size of the particles. However, selective transport of sediments also plays a role in relation to downstream fining: smaller-than average particles are more easily entrained than larger-than average particles, since the shear stress required to entrain a grain is linearly proportional to the diameter of the grain. However, the degree of size selectivity is restricted by the hiding effect described by Parker and Klingeman (1982), wherein larger particles protrude from the bed whereas small particles are shielded and hidden by larger particles, with the result that nearly all grain sizes become entrained at nearly the same shear stress.

Truss (unit)

A truss is a tight bundle of hay or straw. It would usually be cuboid, for storage or shipping, and would either be harvested into such bundles or cut from a large rick.

Markets and law

Hay and straw were important commodities in the pre-industrial era. Hay was required as fodder for animals, especially horses, and straw was used for a variety of purposes including bedding. In London, there were established markets for hay at Smithfield, Whitechapel and by the village of Charing, which is still now called the Haymarket. The weight of trusses was regulated by law and statutes were passed in the reigns of William and Mary, George II and George III. The latter act of 1796 established the weights as follows:

In summary then, the standard weights of a truss were:

and 36 trusses made up a load.

Trussing

A detailed description was provided in British Husbandry, sponsored by the Society for the Diffusion of Useful Knowledge,

This done, he measures the cut to be made in the stack, which is decided by the usual size of the trusses — each being as nearly as possible three feet by two and a half, and thick in proportion to the fineness and closeness of the hay; those of the best quality being the thinnest. He then mounts the ladder and cuts perpendicularly through the thatch, as far down as will produce the requisite number of trusses. This he does with a very strong and sharp knife, about thirty inches in length by nearly six in breadth of the blade, and formed as in fig. 2. The handle is however often made short and straight from the blade, but the form above represented allows of more power being exerted by the workman in cutting through the stack, and it is an operation which demands considerable strength.

Load (unit)

The load (Latin: carrus, lit. "cartload"), also known as a fodder, fother, and charrus, was an English unit of weight or mass of various amounts, depending on the era and the substance being measured.

Lead load

The load of lead was 30 fotmals, 175 stone, or 2,100 Merchant pounds (~918.525 kg).

"The Load of Lead doth consist of Thirty Fotmals, and every Fotmal containeth Six Stone, except Two Pound; and every Stone doth consist of Twelve Pound, and every Pound consisteth of the Weight of 25 Shillings,5 whereby the Sum in the Fotmal is Seventy Pound. But the Sum of the Stones in the Load is Eight Times Twenty and Fifteen, and it is proved by Six Times Thirty which is Nine Times Twenty. But of every Fotmal there are abated Two Pound in the foresaid Multiplication, which are Sixty, which make Five Stone. And so there are in the Load Eight Times Twenty and Fifteen as is aforesaid." - Tractatus de Ponderibus et Mensuris

Straw load

The load of hay or straw was 36 trusses or 1,296 pounds (now about 587.8557 kg).

Bed

A bed ( listen ) is a piece of furniture used as a place to sleep or relax. It has a secondary use as a place to engage in sexual relations.

Most modern beds consist of a soft mattress on a bed frame, with the mattress resting either on a solid base, often wooden slats, or a sprung base. Many beds include a box spring inner-sprung base, a large mattress-sized box containing wood and springs that provide additional support and suspension for the mattress. Beds are available in many sizes, ranging from infant-sized bassinets and cribs, small beds for a single child or adult, to large queen and king-size beds designed for two adults. While most beds are single mattresses on a fixed frame, there are other varieties, such as the murphy bed, which folds into a wall, the sofa bed, which folds out of a sofa, and the bunk bed, which provides two mattresses on two tiers. Temporary beds include the inflatable air mattress and the folding camp cot. Some beds contain neither a padded mattress nor a bed frame, such as the hammock.
