These 9 tips will help you start to get the most out of Excel for engineering. Watch my free training just for engineers. In the three-part video series I'll show you how to easily solve engineering challenges in Excel.

Click here to get started. To eliminate the pain associated with Excel cell references, use Named Ranges to create variables that you can use in your formulas. Not only do they make it easier to enter formulas into a spreadsheet, but they make it MUCH easier to understand the formulas when you or someone else opens the spreadsheet weeks, months, or years later.

To make it easy to update chart titles, axis titles, and labels you can link them directly to cells. If you need to make a lot of charts, this can be a real time-saver and could also potentially help you avoid an error when you forget to update a chart title. To update a chart title, axis, or label, first create the text that you want to include in a single cell on the worksheet.

Next, select the component on the chart. Now, the chart component will automatically when the cell value changes. You can get creative here and pull all kinds of information into the chart, without having to worry about painstaking chart updates later.

Usually, we set up spreadsheets to calculate a result from a series of input values. You could rearrange the equations and make the old result the new input and the old input the new result. You could also just guess at the input until you achieve the target result. Fortunately though, neither of those are necessary, because Excel has a tool called Goal Seek to do the work for you. Select OK, and Excel iterates to find the correct input to achieve the target.

One of the things that makes Excel a great engineering tool is that it is capable of handling both equations and tables of data.

And you can combine these two functionalities to create powerful engineering models by looking up data from tables and pulling it into calculations.

In many instances, they can do everything you need. These two functions allow you to lookup data in any column or row of a table not just the first oneand you can control whether the value returned is the next largest or smallest. This is done by taking advantage of the flexibility of this lookup method to find the x- and y-values immediately before and after the target x-value. Another way to use existing data in a calculation is to fit an equation to that data and use the equation to determine the y-value for a given value of x.

Many people know how to extract an equation from data by plotting it on a scatter chart and adding a trendline. This can result in errors from typos or forgetting to update the equation when the data is changed.This web page lists statistics formulas used in the Stat Trek tutorials.

Each formula links to a web page that explains how to use the formula. Unless otherwise noted, these formulas assume simple random sampling. In the following formulas, X and Y are random variables, and a and b are constants.

The correct formula for degrees of freedom DF depends on the situation the nature of the test statistic, the number of samples, underlying assumptions, etc. Below, the first two formulas find the smallest sample sizes required to achieve a fixed margin of error, using simple random sampling.

The third formula assigns sample to strata, based on a proportionate design. The fourth formula, Neyman allocation, uses stratified sampling to minimize variance, given a fixed sample size.

And the last formula, optimum allocation, uses stratified sampling to minimize variance, given a fixed budget. Browse Site. Statistics Formulas This web page lists statistics formulas used in the Stat Trek tutorials. By convention, 0!Conditional Probability. Permutations nPr for Multiple Subsets.

As with any branch of physics, solving statics problems requires you to remember all sorts of calculations, diagrams, and formulas. The key to statics success, then, is keeping your shear and moment diagrams straight from your free-body diagrams and knowing the differences among the calculations for moments, centroids, vectors, and pressures.

Solving statics problems can be complicated; each problem requires a list of items to account for and equations to create and solve. Solve statics problems with ease by using this checklist:.

In addition to dimensions and angles, you must include four major categories of items on a properly constructed free-body diagram:. Write equilibrium equations to compute as many unknown support reactions as possible. To solve for internal forces, identify the type of structure and write your equilibrium equations. After you identify the type of structure, you then know which technique to use to help you write your equilibrium equations:.

To solve, you can use the method of joints or the method of sections. Beams bending members : Members are loaded with internal axial forces, shear forces, and moments. To solve, cut the member at the desired location, draw a new free-body diagram of the cut section, and write equilibrium equations. To solve, use the blow-it-all-apart approach to break the structure into smaller pieces. Look for internal hinges as common places to separate your structure and draw free-body diagrams to solve for the connecting pin forces.

Cable structures: Members are constructed from axially loaded cables. Compute the cable tension at the location of known maximum sag or vice versa.

Submerged surfaces: Members are subjected to fluid pressure. To solve, draw a free-body diagram of the hydrostatic pressure diagram which is zero at the fluid surface and linearly increases with depth.

Include the weight of the fluid on objects with non-vertical faces. When working submerged surface problems in statics, remember that all submerged surfaces have a fluid acting upon them, causing pressure.

You must compute two pressures: the hydrostatic pressure resultant and the fluid self weight. Hydrostatic pressure resultant: The hydrostatic pressure resultant acts horizontally at 0. To compute the center of area of a region or distributed loadyou can compute the x- coordinate and the other coordinates similarly from the following equations:. For discrete regions: You can break discrete regions into simple shapes such as triangles, rectangles, circles, and so on.

For discrete shapes, creating a simple table such as the one that follows for each coordinate can be useful. You can create as many rows as you need for as many regions as you have. For continuous regions: Continuous regions are usually defined by more complex boundaries, so you must define them with mathematical equations such as the one that follows:.

Shear and moment diagrams are a statics tool that engineers create to determine the internal shear force and moments at all locations within an object. Start by locating the critical points and then sketching the shear diagram.

Order increases from load to shear to moment that is, 1st order load diagram, 2nd order shear, 3rd order moment. If the load area is positive, the change in shear is positive. If the shear area is positive, the change in moment is positive. In many statics problems, you must be able to quickly and efficiently create vectors in the Cartesian plane.

Luckily, you can accomplish your Cartesian vector creations easily with the handy vector formulas in this list:.Learn more about Scribd Membership Home.
