The Machinery Crisis, W T. Brown Jan 1979

The Machinery Crisis, W T. Brown

Journal of the Department of Agriculture, Western Australia, Series 4

The machinery crisis - I believe we have come through a crisis in farming efficiency. To maintain his income, the farmer has had to reduce his costs of production, or increase production per man. He has done this by climbing to a new plateau of efficiency, and he expanded or got out; he has substituted capital for labour.

In many cases this means bigger, more powerful machinery. This is not a simple or easy move and there are many potential ways to mske the wrong decision.


Some Aspects Of Reliability Theory And Life Testing, Danny Laforrest Dunham Jan 1973

Some Aspects Of Reliability Theory And Life Testing, Danny Laforrest Dunham

All Master's Theses

This paper explores the properties of the mean life of an item when an exponential density is assumed for the item's life length. Two different tests are discussed, one where the items are allowed to fail while on test without replacement, and the second test where the items are replaced as they fail. Finally the efficiency of the two tests is explored with respect to the number of items that are allowed to fail versus the length of the test.

Australian Spark Arrester Tests : Test No. Spa-21 : Caterpillar D7 Turbocharger, W F. Baillie, G. H. Vasey

Journal of the Department of Agriculture, Western Australia, Series 4

FORMAL tests on spark arresters are conducted by The Tractor Testing Committee* at the Testing Station, Werribee, on behalf of those Companies concerned with tractors, engines or spark arresters who wish to have these equipments tested.

The arrester is tested on the engine it is specially designed for (as in this instance), or if it is sold for use on any or several engines, it is tested on an engine of the highest power for which the spark arrester is intended.
