Difference between gradual failure and sudden failure
Answers
Explanation:
Differences Between Capital Profit And Revenue Profit. Following are the main differences between capital profit and revenue profit. Capital profit is earned by selling assets, shares and debentures at a price more than their book value and face value. Revenue profit is earned in the ordinary course of the business.
Answer:
A failure in which the device characteristics change slowly; can Range from hours to years; also referred to as gradual fiber.
Sudden Failure. A failure that could not be anticipated by previous examination or monitoring.
Explanation:
Types of Failure
There are two types of failure: i) Gradual failure ii) Sudden failure
Gradual failure
It means slow or progressive failure as the life of the item increases, its efficiency decreases resulting in decreased productivity, increased operating cost, and a decrease in the value of the item, e.g. machines/equipment, etc.
Sudden failure
In this type of failure, the items do not deteriorate markedly with service but ultimately fail after some period of usage, thus precipitating the cost of failure. Sometimes the sudden failure of an item may cause a loss of production or may also account for damaged or faulty products. The period between installation and failure is not constant for any particular type of equipment but will follow some probability distribution that may be progressive, retrogressive, or random in nature.
Progressive failure
Under this mechanism, the probability of failure increases with the increase in the life of an item.
Retrogressive failure
Certain items have more probability of failure at the beginning of their life and as time passes, the chances of failure become less. In other words, the ability of the unit to survive the initial period of life increases its expected life.
Random failure
Under this mechanism, the constant probability of failure is associated with items that fail from random causes such as physical shocks, not related to age.
