For that reason, acceptance testing should be considered any time new machinery is purchased. For instance, a large number of industrial plants have pumps used for a wide range of purposes. Failure of a pump can cause huge problems for the entire production process and result in expensive downtime. How valuable would it be to know the condition of the machinery. To know whether or not it needs maintenance or replacement prior to its failing? With the help of vibration analysis, you can accurately determine the level of degradation and schedule the maintenance to resolve the issues identified. This can provide noteworthy savings. One of the major drawbacks of conventional preventive maintenance programs is the replacement of parts before completion of their anticipated life span. This often results in significant waste of funding for machines or components that are in good operating condition. Predictive maintenance helps to curb this practice by replacing the components only when required, thereby avoiding machine downtime and saving considerable money. Vibration analysis is not simple and requires somewhat sophisticated instruments and software to analyze the data to determine the exact problem(s). However, the investment is paid back many times over within a relatively short time-span with the benefits that it delivers. Studies have shown that a fully implemented condition monitoring program run by trained and certified vibration technicians and analysts can achieve approximately $10.00 savings per dollar invested in the program (including the costs of PdM analyzers, software, manpower and training)! In order to get quality results, organizations often send their maintenance technicians to private organizations that offer vibration analysis certification courses for vibration training. Chimpanzees were used because they're the closest modern-day relative to humans. Four to seven million years ago, humans and chimpanzees diverged from a common ancestor. Researchers taught the five adult chimpanzees to walk on treadmills. They walked upright on their hind legs. Knucklewalked on all fours. The chimps wore masks that tracked how much oxygen they used. The researchers also measured how much pressure was exerted on the treadmill. This revealed which muscles the animals were using. The same measurements were taken for the four adult humans. The walking tests showed that the chimps, as a group, averaged the same energy expenditure walking on all fours as they did walking on two legs. As a group, the humans used 75 percent less energy walking upright than the chimps used walking on all fours. Essentially, walking upright seemed to be beneficial because it saved energy. But what appeared even more interesting was that the amount of energy expended by the chimps varied between them. sigmund freud
