A poll is 10m and weight 600 newton at it's centre of gravity four metre from end (A) and lies on horizontal plane. 1. Draw a diagram acting on the poll when the end (B) is lifted by vertical form
To draw the diagram of the poll when end B is lifted by a vertical force, follow these steps:
1. Start by drawing a horizontal line to represent the ground or the horizontal plane on which the poll lies.
2. Mark a point on the line to represent the center of gravity (CG) of the poll.
3. Measure 4 meters from the center of gravity (CG) towards the left, and mark a point called A. This represents the end A of the poll.
4. Measure 6 meters from the center of gravity (CG) towards the right, and mark a point called B. This represents the end B of the poll.
5. Now, draw a vertical line from point B upwards. This line represents the vertical force applied to lift end B.
6. Label the vertical line with the magnitude of the force applied, if provided in the question.
7. Draw an arrow on the vertical line to signify that it is a force vector. The direction of the arrow should be upwards to indicate the force lifting the end B.
The completed diagram will show the poll lying on the horizontal plane, with the center of gravity (CG) marked and the vertical force applied at end B.
Note: If the magnitude of the vertical force is not provided, you can leave it unspecified or label it as "F" to represent an unknown force.
