mechanical properties and factors of safety of spider draglines

mechanical,properties,factors,safety,spider,draglines Experiments were carried out to determine the strain energy capacity and breaking strain of spider drag-line silk. These properties are discussed in terms of a mathematical model of a spider falling on a drag-line. It was found that the strain energy capacity of the drag-line was insufficient to absorb the potential energy lost by a falling spider and that [...]

Principles of Heat Transfer

the heat flow constitute two basic elements in the design of thermal equipments such as boilers, heat exchangers, nuclear reactor cores, etc.Since in nuclear reactors, under nor-mal opemting conditions, radiation heat transfer has limited application, the present discussion will be mainly focused on conduction and convection heat transfers.
