This means that, in words with more than one syllable, one syllable will sound a little longer and louder than the others. “Syllable stress” refers to the syllable in a word that gets more emphasis than the others. When you say a word that only has one syllable, you only have one syllable to stress. Syllable StressĬlick below to listen to a recording of this passage. For example, the word “outside” has 4 vowels, but only two syllables, because -ou only counts as one vowel sound, while -i…e combine to form the long “i” sound (like in the word “pie”), even though they are separated by a consonant. Some vowel sounds are silent, while other sounds are made up of two different vowels. ![]() Additionally, the number of syllables is not necessarily equal to the number of vowels. While the majority of English words have between 1-4 syllables, some words have as many as 19! This means that counting the number of syllables is not always easy. All ig at or – 4 syllables, 4 vowels (All-i-ga-tor).T om orr ow – 3 syllables, 3 vowels (To-mor-row).Ord er – 2 syllables, 2 vowels (Or-der).Therefore, the effective reading would hence be Main scale reading + Vernier scale reading-(zero error). It can be of two types: when the Vernier scale is towards numbers greater than 0 on the main scale then the error is positive, whereas if the Vernier scale is towards the plain region before 0 on the main scale then the zero error is negative. Zero error can be understood as the condition where the Callipers register a reading when there should not be any reading or when the main scale and the Vernier scale are supposed to read 0 and coincide with each other but do not do so. Note: Note that the readings that we obtained are without accounting for any zero error. ![]() To this end, the effective reading will be the sum of the main scale and Vernier scale readings and is equivalent to 44mm+0.6mm = 44.6mm. We see that the zero of the Vernier scale is closest to the fourth division after 40, i.e., the $44^$ division. ![]() To obtain the main scale reading: Each division on the main scale represents 1mm. We can obtain the resultant reading in just two steps:ġ. Let us now examine the image of the Vernier calliper given to us. The interpolated reading is obtained by observing which line of the Vernier scale coincides with a line on the main scale. It consists of the main scale which is the mm scale, and the Vernier scale that slides over the main scale and gives interpolated readings to a precision of 0.1mm. The outer jaw holds the object whose dimensions we have to measure and measures the external diameter or width of an object, while the inner jaw is smaller and is used to measure the internal diameter of an object. A calliper usually consists of an inner jaw and an outer jaw. Add these two together to obtain an effective reading.įormula used: Final reading = Main scale reading + Vernier scale readingĪ Vernier Calliper is an instrument that is used to make very accurate linear measurements. The division to which the zero on the Vernier scale is closest to is the main scale reading, and the division of the Vernier scale that first coincides with a division on the main scale gives the Vernier scale reading. Hint: Recall that each division on the main scale represents 1mm and each division on the Vernier scale represents 0.1mm.
