There are a number of things that can cause your car stereo to lose its reception quality, but this is one of the most common and easily remedied. The problem: a loose radio antenna.

### Percent word problems

Sounds too stupid to be true, but if your car has a long, stiff "whip" style antenna, as many cars today come with, it could just be loose, causing you to get static. The antenna screws into its base on the fender just like anything else. All you need to do is check it for tightness. If it's loose, hand tighten it then give it a little extra nudge with a wrench or pliers careful not to scratch the paint!

If it was loose, you'll be bathed in static free car stereo sound once again. Matthew Wright.

To find the median, you must first arrange the observations in an ascending or descending order. Case 1. When the number of observations is odd, the median is the middle value.

The number of point values is 7, an odd number. Hence, the median is the value in the middle position. Case 2. When the number of observations is even, the median is the average of the two middle values. The number of point values is 8, an even number.

Hence the median is the average of the 2 middle values. Try the free Mathway calculator and problem solver below to practice various math topics. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations.

Want to see this answer and more? It is resting onIn statistics, mode, median and mean are typical values to represent a pool of numerical observations.

They are calculated from the pool of observations. Mode is the most common value among the given observations. For example, a person who sells ice creams might want to know which flavor is the most popular.

Median is the middle value, dividing the number of data into 2 halves.

Il buio in sala: recensione v/h/sMean is the average of all the values. For example, a teacher may want to know the average marks of a test in his class. The mode of a set of observations is the value that occurs most frequently in the set. A set of observations may have no mode, one mode or more than one mode. If the observations are given in the form of a frequency table, the mode is the value that has the highest frequency. Note: The above example shows that a set of observations may have more than one mode.

There are 8 number cards with values 0 — 7. Each time a card is drawn at random and the card value is recorded. The frequency refers to the number of times a value is shown. The following frequency table shows the marks obtained by students in a quiz. Given that 4 is the mode, what is the least value for x?

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.

## Method of Sections | Analysis of Simple Trusses

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:. Force vectors and distance vectors are the most basic vectors that you deal with.If you're seeing this message, it means we're having trouble loading external resources on our website.
