For example, Paraffin has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).
This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminium or plastic, [8] and can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area (the teeth). There are four types: internal, external, combination ...
The washer was recalled with a class-action lawsuit [86] and pulled off the market. A Beko washing machine; modern household washing machines start at 1 kg (2 lb) capacity, designed for smaller households, and span to 24 kg (53 lb) load capacity. In 2003, Maytag introduced their top-loading Neptune TL FAV6800A and TL FAV9800A washers. Instead ...
This type of truss is seen in a framed roof consisting of rafters and a ceiling joist, [13] and in other mechanical structures such as bicycles and aircraft. Because of the stability of this shape and the methods of analysis used to calculate the forces within it, a truss composed entirely of triangles is known as a simple truss. [14]

The king post is the central, vertical member of the truss. Crown posts in the nave roof at Old Romney church, Kent, England. A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below).
The resistance of copper wire is approximately 1 ohms / 1000 feet for 10 AWG, 10 ohms / 1000 feet for 20 AWG, 100 ohms / 1000 feet for 30 AWG, and so on. [ 5 ] : 27 Because aluminum wire has a conductivity of approximately 61% of copper, an aluminum wire has nearly the same resistance as a copper wire that is two sizes ...
Young's modulus is also used in order to predict the deflection that will occur in a statically determinate beam when a load is applied at a point in between the beam's supports. Other elastic calculations usually require the use of one additional elastic property, such as the shear modulus G {\displaystyle G} , bulk modulus K {\displaystyle K ...
