False.** Using a ruler to measure a box directly involves placing the ruler in contact with the object, which is a form of direct observation. - **e. False.** Even with the correct instrument, errors can occur, and the true value might not be known due to systematic or random errors. - **f. False.** In technical terms, a mistake is a human error that can usually be corrected, while an error is a deviation from the true value and can be systematic or random. - **g. False.** Natural errors often arise from environmental factors and not necessarily from human senses. Human errors caused by senses are typically classified as mistakes. - **h. False.** The three types of errors typically discussed in surveying are systematic, random, and human errors, not unknown errors.Refer to this guide to understand common misconceptions

FEA for Dynamic Problems

Finite element analysis or FEA is a computational tool that evaluates the approximate solution for a particular engineering problem. The tools provided by FEA help to evaluate the solutions of partial differential equations (PDEs) computationally following a numerical approach. Solutions of the PDEs can also be performed by following traditional algebraic approaches, but when the problem gets towards the complex side, it becomes very tedious and almost impossible to arrive at the solutions. In such cases, the FEA fulfills the purpose by evaluating the equations following multiple time steps and iterations. The more the time steps and iterations, the more accurate the solution. The solution plotted by FEA analysis and mathematical approaches varies asymptotically.

### True or False Statements in Surveying

Evaluate the following statements to determine if they are true or false. If a statement is false, provide an explanation.

#### Statements:

a. **____** The most important quality for handwritten notes in surveying is clarity.

b. **____** If a mistake is found in the handwritten notes it must be erased completely.

c. **____** Regarding surveying data, usually less data is considered better to avoid having too much information and get confused.

d. **____** Using a ruler to measure a box in front of you is an example of an indirect observation.

e. **____** The true value of an observation can be known if you use the correct instrument to measure it.

f. **____** In technical terms, mistake and error are practically the same thing.

g. **____** Natural errors are those caused by the human senses (such as sight and touch).

h. **____** There are three types of error discussed in class: systematic, unknown, and random errors.

i. **____** Random errors tend to partially cancel themselves in a series of observations.

j. **____** A discrepancy is the difference between two observed values of the same quantity.

#### Explanation for False Statements:

- **b. False.** In surveying, mistakes in handwritten notes should be corrected in a manner that maintains the original entry and shows the correction clearly, rather than erasing it completely.

- **c. False.** In surveying, more data is generally considered better as it provides a more accurate and reliable dataset, reducing uncertainty and potential errors.

- **d. False.** Using a ruler to measure a box directly involves placing the ruler in contact with the object, which is a form of direct observation.

- **e. False.** Even with the correct instrument, errors can occur, and the true value might not be known due to systematic or random errors.

- **f. False.** In technical terms, a mistake is a human error that can usually be corrected, while an error is a deviation from the true value and can be systematic or random.

- **g. False.** Natural errors often arise from environmental factors and not necessarily from human senses. Human errors caused by senses are typically classified as mistakes.

- **h. False.** The three types of errors typically discussed in surveying are systematic, random, and human errors, not unknown errors.
