embodiment design: find suitable hardware within technical and economic constraints (which is just practicalisation). ... new products are truly the lifeblood of a company's long-term economic existence.

The following is essential background to practical welded joint design :-. Economic Design of Weldments, Technical Note No.8, AWRA (now the WTIA).

requiring maintenance to restore its effectiveness, until. eventually it reaches the end of its economic life and is retired. ... The life stages sketch emphasises the importance of creativity and economics in design, and of the technical specifications

The sketch only goes so far as to identify the causes and effects between related factors in this study in the field of Agricultural Economics.

w. must equal t. s. /η. However it is most unusual for the economics to justify increase of bar thickness locally in way of the joint - the whole bar must therefore

Clearly in designing such brakes, the economics and reliability of more complex mechanisms must be considered.

Before an economic motor can be selected to drive a load, the load's steady state torque-speed characteristic should be known - this may be generalised by :. ( 1a ) T = T. 0. ... So it makes economic sense to develop torque in a mechanical transformer

width. Proportions may be expressed as :-. ( 16 ) f = β m where, usually, 9 β 15 for economic gears -. These limits should not be regarded as inviolable, but costs should be expected

But the probability of the gears surviving 75 kW with an economic life is low. ... economics. To put lives in perspective, a life of 1000 khr represents more than a century of continuous running - all day, every day!

So the design of a power transmission train in practice needs to be carefully balanced from an economic point of view. ... the table here) and economic belt replacement frequency, or with the usual commercial expectation of 26 kh.

The economics in particular must be attractive. Remember always the ubiquity of the cost equation :. total costs = first costs running costs. in which costs are typically discounted cash flows. ... A further example of economic analysis is shown; it

Design factors are increased also when the consequences of failure - economic, social, environmental or political - are serious.

Apart from giving a clearer understanding of the mechanics involved in power transmission by belting, the model enables part- and no-load tensions to be evaluated, and more economic drives chosen.

There may be a number of different solutions to this, each with its own set of raw materials, chemical reactions, economics and so on.

It is. all the more economic as the number of degrees of freedom of the system is high.
