How to Calculate the Mechanical Advantage of a Machine (Physics)

Mechanical advantage is a very important parameter of machines and is considered a lever problem.

Mechanical advantage is the ratio of load to effort.

Nickzom Calculator – The Calculator Encyclopedia solves for mechanical advantage alongside a bunch of other problems in Physics.

For Example: Let’s calculate mechanical advantage of a machine when the load is 200 N and the effort is 120 N.

Mechanical Advantage = Load / Effort

Load = 200 N

Effort = 120 N

Mechanical Advantage = 200 / 120 = 1.6667

Therefore, the mechanical advantage of the machine is 1.6667.

How to Solve and Calculate the Mean or Average of Discrete and Continuous Numbers

Mean is a measure of central tendency and is considered to be a very important parameter of statistics. Mean or Average is the sum of the data sets or numbers or values divided by the number of numbers or data sets or values.

What is a discrete number?

A discrete number is a standalone number. It might be a whole number or fractional number but it stands on its own with no extension or range. An example of a discrete number is 5, 12, 10.6, 17, 20

What is a continuous number?

A continuous number is a range of numbers packaged as a single entity. An example of a continuous number is 5 – 10, 20 – 30, 25 – 50.

There are two possibilities in calculating the mean of a set of discrete numbers. One can either compute the mean via the application of frequency or no frequency at all.

For Example: A set of discrete numbers such as these:

4, 5, 6, 7, 8, 9

These numbers all occur once and have a frequency of 1 per number.

Therefore, if you want to create a table for the number and frequency, it looks like this:

Number        4, 5, 6, 7, 8, 9

Frequency    1, 1, 1, 1, 1, 1

You can clearly see that there is no need for applying frequency to calculate the mean of the above set of numbers. Application of frequency on a large set of numbers makes it easier to organize and compute the mean.

Now, for a set of numbers such as these:

4, 4, 4, 2, 4, 5, 3, 3, 3, 2, 1, 1, 6, 4, 3, 2, 4, 2, 5, 2, 1

You can see that some of the discrete numbers occur more than once and this implies that application of frequency is useful and makes the computing of mean easier and comprehensive.

From the display of numbers above you can see that the number 4 occurred times, the number 2 occurred times, the number 5 occurred 2 times, the number 3 occurred 4 times, the number 1 occurred 3 times, the number 6 occurred 1 time.

The Effect of Financial Calculations in the Nigerian Economy

It is true that tiny drops of water can make an ocean but time interval at which it drops and its consistency are the keys. No child becomes an adult within the space of one year. It takes several years of growth and development for that dream to become an obvious reality. One is not left in the dark on the effect of financial calculations in the economy except they’ve chosen to be intentionally blind to its truth.

The economy of a nation or a person can be affected in no small way by certain financial calculations like taxes,charges etc both positively and negatively depending on who receives and who gives. A nation involved in international trade have the responsibility of paying certain levies saddled on her shoulder, some of which might be too high and could possibly devalue her currency.

Business owners also owe it to certain government bodies to pay taxes at a fixed rate which might possibly increase with the fleeting of years and takes no consideration of the woes and fortunes of the business owner per time. Though it is a decent source of fund that can be cruel to those it is being sourced from,revenues are being generated when these funds are invested in certain sectors that have been known for wholesale delivery of bountiful returns,which in turn can serve as a means of giving back to the society and people who labour to make policies, enforce and carry it out in different strata of the working sector.

How To Get Answers and Steps For a Function of a Function Differentiation (Calculus) Problem Using The Calculator Encyclopedia

According to Wikipedia,

In mathematicsdifferential calculus is a sub-field of calculus concerned with the study of the rates at which quantities change. It is one of the two traditional divisions of calculus, the other being integral calculus, the study of the area beneath a curve.

Nickzom Calculator calculates function of a function for the following formats:

    • (expression)n
    • k(expression)n
    • sin(expression)
    • ksin(expression)
    • cos(expression)
    • kcos(expression)

The Calculator Encyclopedia Converts Units of Illumination in Light Conversions

According to Wikipedia,

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylightDaylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

The calculator encyclopedia converts 12 units of illumination. These units are:

  • Lux
  • Meter-Candle
  • Centimeter-Candle
  • Foot-Candle
  • Flame
  • Phot
  • Nox
  • Candela Steradian/sq. m
  • Lumen/sq. m
  • Lumen/sq. cm
  • Lumen/sq. ft
  • Watt/sq. cm (at 555nm)

To commence this conversion, proceed to the Calculator Map, click on Light Switches under Switches (Unit Conversion).

Nickzom Calculator Calculates Permutation and Combination With Steps – The Calculator Encyclopedia

According to Wikipedia,

In mathematics, the notion of permutation relates to the act of arranging all the members of a set into some sequence or order, or if the set is already ordered, rearranging (reordering) its elements, a process called permuting.

In mathematics, a combination is a selection of items from a collection, such that (unlike permutations) the order of selection does not matter.

The Importance of STEM (Science, Technological, Engineering and Mathematics) in Nigeria

Every new development, be it positive or negative has its importance and disadvantages as well. Its importance gives it a penetration advantage to be valued and appreciated in spite of its disadvantages. Just like the reality of sickness created opportunities for doctors to be valued and appreciated in their sphere of influence for saving lives, Science, Technology, Engineering and Mathematics have not done any less. Not only does it create opportunities, it also suggests ways those opportunities can be harnessed.

 

In our present age of growing advancement, the importance of STEM (Science, Technology, Engineering and Mathematics) cannot be overemphasized as its relevance finds expression in our day to day activities as humans ranging from the alarm clocks that greet us in the morning, the alarm bells that alerts us of a visitor, the automobiles that convey us to our places of work and the stair lifts that finally lands us on the floor of our offices. Its importance is not only appreciated in the industries, roads and all other obvious infrastructure where it is easily spotted but has also been domesticated such that some equipment used in the preparation of sumptuous meals owe its allegiance to them.
