What will happen to a material if the stress exceeds the ultimate strength?
It will break or fail. The type of failure will depend on how brittle/ductile it is. Brittle material will break cleanly, while ductile material will deform to varying degrees.
What are the application of partial differentiation in engineering?
It is use to fail the students in exams
What process causes a material to break due to excess stress?
Either deformation in a plastic material, or fracture in a brittle one. Oddly enough, a short bolt, tested to failure in a testing machine, will fail in the thread region due to the stress points inherent in the thread form. Long bolts on the other hand, will fail in the shank. This is usually explained by the idea that the bolt shank will break at its weakest point, and the longer the bolt, the more of the weak points, and the more of them, the weaker will be the weakest of them.
What influence the choice of materials for marine engineering component?
It is important to that we understands the specific usage of a certain material, the conditions on where the materials is likely to fail and how to effect an efficient repair. Bad materials mean accidents, and accidents cost lives as well as a lot of money, or possible loss of ship.
Why Software doesn't wear out explain?
Hardware Failure Rates The illustration below depicts failure rate as a function of time for hardware. The relationship, often called the "bathtub curve," indicates the typical failure rate of individual components within a large batch. It shows that in say a batch of 100 products, a relatively large number will fail early on before settling down to a steady rate. Eventually, age and wear and tear get the better of all them and failure rates rise again near the end of the products life. To assist in quality control, many new batches of products are 'soak' tested for maybe 24 hours in a hostile environment (temperature/humidity/variation etc.) to pinpoint those that are likely to fail early on in their life, this also highlights any inherent design/production weaknesses. These early failure rates can be attributed to two things • Poor or unrefined initial design. Correcting this, results in much lower failure rates for successive batches of the product. • Manufacturing defects i.e. defects in the product brought about by poor assembly/materials etc. during production. Both types of failure can be corrected (either by refining the design, or by replacing broken components out in the field), which lead to the failure rate dropping to a steady-state level for some period of time. As time passes, however, the failure rates rise again as hardware components suffer from the cumulative effects of dust, vibration, abuse, temperature extremes and many other environmental maladies. Stated simply, "…The hardware begins to wear out."Software Engineering Topic 1 Page 10 Software Failure Rates Software is not susceptible to the same environmental problems that cause hardware to wear out. In theory, therefore, the failure rate curve for software should take the form shown below. Undiscovered defects in the first engineered version of the software will cause high failure rates early in the life of a program. However, these are corrected (hopefully without introducing other errors) and the curve flattens as shown. The implication is clear. Software doesn't wear out. However, it does deteriorate with maintenance as shown below. During its life, software will undergo changes and it is likely that some new defects will be introduced as a result of this, causing the failure rate curve to spike as shown above. Before the curve can return to the original steady-state failure rate (i.e. before the new bugs have been removed), another change is requested, causing the curve to spike again. Slowly, the minimum failure rate level begins to rise-- the software is deteriorating due to change. Thanks & Regards, Bastin Vinoth NG
What will happen if corrupt master boot record?
If the master boot record (MBR) becomes corrupted, the computer may not be able to boot properly. This can lead to issues such as a "missing operating system" error or a boot loop. To fix this, you may need to repair the MBR using tools like the Windows Recovery Environment or third-party software.
What will happen to a person if his neurons fail to produce neurotransmitters?
The nervous system can't transmit messages without neurotransmitters. A person will die if his neurons fail to produce them.
What happen if you fail?
You absolutely fail and you get an "F"
Can the battery going dead in a '93' Lumina cause some sort of computer error where the damper doors on the air system fail to operate?
Not usually.
What happens to companies that fail to maintain an adequate system of internal control?
Company may be subject to charges of fraud
What is a fail passive and a fail operational auto pilot system in aircrafts?
Fail-passive Automatic Landing System An automatic landing system is fail-passive if, in the event of a failure, there is no significant out-of-trim condition or deviation of flight path or attitude - but the landing is not completed automatically. NOTE: For a fail-passive automatic landing system the pilot assumes control of the aircraft after a failure. The following are typical arrangements: (1) A monitored automatic pilot in which automatic monitors will provide the necessary failure detection and protection. (2) Two automatic pilots with automatic comparison to provide the necessary failure detection and protection. Fail-operational Automatic Landing System. An automatic landing system is fail-operational if, in the event of a failure, the approach, flare and landing can be completed by the remaining part of the automatic system. NOTE: In the event of a failure, the automatic landing system will operate as a fail-passive system. The following are typical arrangements: (1) Two monitored automatic pilots, one remaining operative after a failure. (2) Three automatic pilots, two remaining operative (to permit comparison and provide necessary failure detection and protection) after a failure.
Can car still fail emissions if check engine light is off?
Yeah, it can. If something is wrong with your emmision control system, your car can still fail emmisons, but the check engine light doesn't have to be on.
Can the safety on a pistol fail?
ANY mechanical system- including the safety on a firearm- CAN fail. This is the reason for the basic firearm safety rules- including "do not point a firearm at anything you do not mean to shoot." It is rare, but CAN happen.
What will happen if one part of the system fail to carry out their corresponding function?
That part will not function. It depends on the system how bad the nonfunctional part will affect it. For example it could stop the heart.
What should you do if your car's electric signals fail to operate?
change the flasher "relay"
What Computer that continues to operate when one of its components fail?
Fault-tolerant computer
How does the nervous system affect other systems?
it is the control centre for the body, if it fails, all the other bodily systems fail, they shutdown, you die
