Using the north lines for reference at both points, use angle rules and/or trigonometry to calculate any angles that are required.

Using your protractor, place the zero of the scale on the north line and measure the required angle clockwise, make a mark on your page at the angle needed.

How tomeasure a bearingMaths

A ship sails 7 km due east from a point P to point A. It then sails 3 km due south from A to point B. Calculate the bearing of B from P.

Removing the manual effort from lubrication means that a considerable amount of time is saved that would have been spent performing maintenance. This means that workers are free to perform other tasks such as proactive monitoring, and reduces machine downtime.

6. A boat sails 8 km north from P to Q and then sails 6 km west from Q to R. Calculate the bearing of R from P. Give your answer to the nearest degree.

Drawing a north line at B and extending the line from A to B shows us a corresponding angle. If we travel from A to B, we need to turn another 180^{\circ} to return back to A. 180^{\circ} + 70^{\circ} = 250^{\circ}

Auto bearing greasers, or automatic lubricators, ensure that components receive the right amount of lubrication, at exactly the right time, removing the margin for human error and preserving the lifespan of machine components.

Make a scale drawing of a point Q 8 km away from a point P on a bearing of 110^{\circ} from P, using a scale of 1 cm : 2 km.

If the angle is more than 180^{\circ} and you do not have a full circle protractor then you should subtract the required angle from 360^{\circ} , and then measure this angle anticlockwise from the north line.

Drawing a line from P to B forms a right angled triangle. Use trigonometry to find the angle APB. Then add this to 90^{\circ} .

Auto Bearing Greasers, also called Automatic Lubricators, take the manual effort out of lubricating bearings. Excellent for difficult to access points, Lubricators can be set to dispense the right amount of lubricant at the correct intervals and over a period of time, saving on lubricant and ensuring that the bearing doesn't get over-lubricated. Using automatic lubricators can also help improve worker safety, machine reliability and maintenance efficiency.

Using the north lines for reference at both points, use angle rules and/or trigonometry to calculate any angles that are required.

For machinery which is operating in harsh conditions, or in dangerous and hard to reach locations, performing maintenance can be risky.

With 36% of premature bearing failures attribute to improper lubrication, it is essential to ensure that components receive the correct quantity of lubrication at the right interval to give the component the best chance of achieving a full service life.

Draw a line from the start point in the direction of the bearing. If you are producing a scale drawing and know the distance to locate a point use this scale appropriately.

Bearings is part of our series of lessons to support revision on loci and construction. You may find it helpful to start with the main loci and construction lesson for a summary of what to expect, or use the step by step guides below for further detail on individual topics. Other lessons in this series include:

{{\tan }^{-1}}\left( \frac{3}{7} \right)=23^{\circ} to the nearest degree (bearings are normally given to the nearest degree)

This north direction is usually provided in the maths exam question. We then measure the required angle in a clockwise direction. All bearings need to be given in three figures, so if the angle measured is less than 100 degrees, we must start the three-figure bearing with a zero.

Bearings are used by sailors and pilots to describe the direction they are travelling. They are also used on land by hikers and the military.

2Using your protractor, place the zero of the scale on the north line and measure the required angle clockwise, make a mark on your page at the angle needed.

Using an automatic lubricator means that no manual effort is required, reducing the risk of injury within the workforce.

A common error is to use the anticlockwise angle as the bearing.E.g.The bearing of B from A is 080^{\circ} , a common mistake would be to use the co-interior angle as the back bearing of A from B as 100^{\circ} , calculating clockwise, the bearing of A from B should be 260^{\circ} .

Using your protractor, place the zero of the scale on the north line and measure the required angle clockwise, make a mark on your page at the angle needed.

We need the angle around the point P clockwise from the north line. We know that angles on a straight line add to 180^{\circ}. 180^{\circ} + 53^{\circ} = 233^{\circ}
