Answer:
Accuracy and precision allow us to know how much we can rely on a measuring device readings. ±.001 as a "accuracy" claim is vague because there is no unit next to the figure and the claim fits better to the definition of precision.
Explanation:
Accuracy and Precision: the golden couple.
Accuracy and precision are key elements to define if a measuring device is reliable or not for a specific task. Accuracy determines how close are the readings from the ideal/calculated values. On the other hand, precision refers to repeatability, that is to say how constant the readings of a device are when measuring the same element at different times. One of those two key concepts may not fulfill the criteria for measuring tool to be used on certain engineering projects where lack of accuracy (disntant values from real ones) or precision (not constant readings) may lead to malfunctons and severe delays on the project development.
±.001 what unit?
The manufacturer says that is an accuracy indicator, nevertheless there is now unit stated so this is not useful to see how accurate the device is. Additionally, That notation is more used to refer to device tolerances, that is to say the range of possible values the instrument may show when reading and element. It means it tells us more about the device precision during measurments than actual accuracy. I would recommend the following to the dial calipers manufacturers to better explain its measurement specifications:
- Use ±.001 as a reference for precision. It is important to add the respective unit for that figure.
- Condcut test to define the actual accuracy value an present it using one of the common used units for that: Error percentage or ppm.
Answer:
Backdoor
Explanation:
The back door fragment in a program allows user to access backdoor information without necessarily following the common security procedures needed. In this case, once the programmer keys in the username he or she logs in without putting password. Therefore, this is a backdoor fragment.
Answer:
15300 N
Explanation:
= Density of air at inlet
= Mass flow rate = 60 kg/s
= Inlet velocity = 225 m/s
= Density of gas at outlet = 
= Inlet area
= Outlet area = 
Since mass flow rate is the same in the inlet and outlet we have
Thrust is given by
The thrust generated is 15300 N.
Answer:
The answer is "Both A and B" are right
Explanation:
During the previous twenty years car producers have made significant advances in planning vehicle structures that give more noteworthy tenant insurance in planar accidents (Lund and Nolan 2003). Be that as it may, there has been little agreement with respect to the significance of rooftop strength in rollover crashes, just as the best strategy for surveying that strength. In 2006 one-fourth of lethally harmed traveler vehicle tenants were associated with crashes where vehicle rollover was considered the most hurtful occasion (Protection Establishment for Expressway Wellbeing, 2007). Numerous lethally harmed tenants in rollovers are unbelted, and some are totally or mostly launched out from the vehicle (Deutermann 2002).
There is difference concerning how underlying changes could influence launch hazard or the danger of injury for inhabitants who stay in the vehicle, paying little mind to belt use.
From an isometric view orientation resource, the four (4) typical characteristics of a front view include the following:
- The front view graphically shows the length and height of an object
- The front view has the least amount of hidden lines.
- The front view must be chosen first.
- The front view's orientation influences the other views.
<h3>What is an isometric sketch?</h3>
An isometric sketch is also referred to as an isometric drawing and it can be defined as a graphical (pictorial) representation of a physical object in technical and engineering drawings, especially by drawing all its three dimensions (3D) at full scale.
<h3>The five characteristics of isometric sketches.</h3>
In technical and engineering drawings, the five (5) characteristics of isometric sketches include the following:
- The final image isn't distorted.
- The image is in three dimensions (3D).
- The final image is drawn to full scale.
- The image are all uniformly foreshortened.
- They are drawn using vertical lines and horizontal lines.
