I've watched it :)
Answer with Explanation:
There are various factors that needed to be taken into account while deciding the factor of safety some of which are summarized below as:
1) Importance of the structure: When we design any structure different structures have different importance in our society. Take an example of hospital, in case a natural disaster struck's a place the hospital should be the designed to withstand the disaster as it's role in the crisis management following a disaster is well understood. Thus while designing it we need it to have a higher factor of safety against failure when compared to a local building.
2) Errors involved in estimation of strength of materials: when we design any component of any machine or a structure we need to have an exact idea of the behavior of the material and know the value of the strength of the material. But many materials that we use in structure such as concrete in buildings have a very complex behavior and we cannot estimate the strength of the concrete absolutely, thus we tend to decrease the strength of the concrete more if errors involved in the estimation of strength are more to give much safety to the structure.
3) Variability of the loads that may act on the structure: If the loads that act on the structure are highly variable such as earthquake loads amd dynamic loads then we tend to increase the factor of safety while estimating the loads on the structure while designing it.
4) Economic consideration: If our project has abundant funds then we can choose a higher factor of safety while designing the project.
Answer and Explanation:
Calibration can be defined as a process where the accuracy of an instrument is measured and are compared with the known and set standards for calibration.
The instrument errors can be defined any deflection from the true value in the measurement or we can say that any difference between measured value and actual or true value results in instrument errors.
The instrument errors are further classified into 4 types:
a). Random errors
:
These error arise as the result of random, unpredictable or irregular changes in an experimental set up.
b). Systematic errors
:
These errors arises as a result of fault in the instrument or as a result of the effects of some external factors.
c). Gross errors:
These errors are a result of human errors in measurement while recording the reading, etc
d). Zero errors:
This error arises when the reading of the instrument is false while the measured value is equal to zero.
This is when the needle of an ammeter or voltmeter is not at zero but somewhere above or below it when the supply is not given.
Answer: hello some aspects of your question is missing below is the missing information
The gas tank is made from A-36 steel and has an inner diameter of 1.50 m.
answer:
≈ 22.5 mm
Explanation:
Given data:
Inner diameter = 1.5 m
pressure = 5 MPa
factor of safety = 1.5
<u>Calculate the required minimum wall thickness</u>
maximum-shear-stress theory ( σ allow ) = σγ / FS
= 250(10)^6 / 1.5 = 166.67 (10^6) Pa
given that |σ| = σ allow
3.75 (10^6) / t = 166.67 (10^6)
∴ t ( wall thickness ) = 0.0225 m ≈ 22.5 mm
Answer:
No it is not a problem
Explanation:
It is not a problem because the stress intensity factor K would approach infinity as you get close to a crack tip and the intensity factor would approach Zero as you get too far away from the crack tip and this is simply because a crack is a notch with zero tip radius .
and The application of stress intensity factor k in respect to present fatigue crack tip is termed " linear elastic fracture mechanics "
