As a rule, the tariff

**plan**is prescribed in the contract that you sign with the provider. Find the contract and look for it this information. Including in the agreement or the Annex, you will likely be able to find the details of your tariff**plan**. Typically, this data transfer rate information, included in the tariff**plan**the volume of traffic and other useful information. All this will help you decide in the event**the plan**yuemei change tariff**plan**or if you just want to know the amount of traffic included in your tariff**plan**. In the contract you can find the phone service provider in case if you need to clarify any information.2

You can also call the company providing you the services for Internet access, and to specify the staff name and details of your tariff

**plan**. In this case you can advise on the benefits of this or that tariff**plan**and to help make the right choice, if you find it difficult to do it yourself. This method is best suited to those who are not very well versed in computer subjects. Then, in this case help and hint from a competent specialist will be very useful.3

Another way to find out your tariff

**plan****of the Internet**is the following: if the website of your provider is the service "my account" and you have a username and password to access this part of the site, you can go and find out the name of your tariff**plan**. You can also learn other necessary and useful information, for example, the amount of traffic downloaded during a certain period, the amount of charges and the recommended date of the next payment. Many providers also allow a "Personal account" to pay for Internet access through electronic payment systems or by credit card.# Advice 2: How to build a plan speeds

**Plan**

**speeds**are built to solve the problem of determining the

**velocity**of the body points graphically. In mathematics and descriptive geometry it is a diagram in which the direction of the velocity (V) of points of a rigid body or a particular mechanism are deposited from a single location at a given scale.

1

**The plan**was characterized by certain properties: it is always mutually perpendicular segment that connects the end of the directed points on the surface of the body segment that connects these points. The length of the segments that join the end of the velocity vectors of certain points of the body, is proportional to the length of segments that join corresponding to these vectors point.

2

The more the scale of the plan, in which the vectors V, the more accurate will the answer to the problem being solved, respectively, at the smaller scale obtained during the measurement and subsequent calculation, the answer will be approximate.

3

How to build a geometric plane, it is easiest to explain on specific example, as the building and further calculation in each case is different. Overall, the construction of such a plan need to know at least a speed of at least one of the points of a shape or mechanism, and the direction of the velocity vector of any other point of the plot.

4

Let ABC, there is a mechanism, consisting of rods connected by hinges. Let the speed of t is known and equal to 2 m/s, and V is a perpendicular bisector to the segment HS and the vector B is perpendicular to AB. You want to find the speed of the T. B.

5

The random point put the pole mechanism - so On, and then select the desired scale. Further, the vector V t need to move to the beginning of this vector coincides with T. O, and need to move it in parallel. Draw a straight OD that will start from the pole and is perpendicular to the line BA.

6

From the end of the vector V T. To draw a straight line, which is perpendicular to BV. A direct cross another OD. The point at which the data straight intersect, determine how used.

7

From the resulting cut On and calculate the speed, etc B: to do this, accurately measure the length of line About, and then multiply its length with the scale of the drawing in relation to the real body or parts - get the speed module of T. B
