The grain direction is known as the machine direction (MD), while the cross direction (CD) is the direction of the paper at right angles to the MD.

The grain direction is known as the machine direction (MD), while the cross direction (CD) is the direction of the paper at right angles to the MD. Correct Answer True

The given statement is true. The grain direction is known as the machine direction (MD), while the cross direction (CD) is the direction of the paper at right angles to the MD. The grain of paper must be taken into account in measuring all physical properties. Most of the physical properties of paper depend on direction, that is, the MD, CD and thickness direction (z-direction).

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. If you are a poet, you will have no difficulty seeing the cloud floating in this sheet of paper. P. So we can say that the cloud and the paper are inter-related. Q. That explains why the cloud is essential for the paper to exist. R.  If the cloud is not here, the sheet of paper cannot be here either.  S. If there are no clouds, there will be no rain; and if there is no rain, the trees will not grow; and if there are no trees, we cannot make paper. 6.  If we look into this sheet of paper even more deeply, we can see the sunshine in it.
