Soal ALAT Ukur Mekanik Kelas X Otomotif

The correct answer is Dial gauge. Dial gauge is a tool used to measure the roundness and concentricity of a wheel rim. It is specifically designed for measuring the accuracy and precision of wheel rims. Micrometer is used to measure the thickness of objects, Vernier Caliper is used for measuring length, and Cylinder gauge is used for measuring the inner diameter of cylinders.

The short needle on the dial gauge will move one notch if the long needle moves one full rotation.

The answer is 203,75 mm because it is the highest measurement among the given values.

The correct answer is "Menunjukkan nilai angka desimal hasil pengukuran." The function of the thimble scale on a micrometer is to show the decimal value of the measurement result. The thimble scale is used to make precise measurements by rotating it to align with the reference line on the sleeve scale. This allows for accurate readings of the decimal value of the measurement.

The main function of a vernier scale is to increase the accuracy of measurements by providing decimal readings. It allows for more precise measurements by providing a secondary scale that can be aligned with the primary scale, allowing for readings to be taken at a finer resolution. This is particularly useful when measuring objects with small increments or when high precision is required.

The correct answer is Jangka sorong. Jangka sorong is the first measuring tool used when measuring the diameter of a cylinder if the type of engine is not known. It is a versatile tool that can measure both inside and outside dimensions accurately. Feeler gauge is used to measure small gaps or clearances, cylinder bore gauge is used to measure the diameter of the cylinder bore, and micrometer is used for precise measurements of small objects.

The correct answer is 20. Pada jangka sorong dengan ketelitian 0,05 mm, skala verniernya terbagi menjadi 20 ruas. This means that there are 20 divisions on the vernier scale of the caliper with an accuracy of 0.05 mm.

Setiap ruas pada skala utama inchi jangka sorong nilainya adalah 1/16 inch. This means that each division on the main scale of the vernier caliper represents a measurement of 1/16 inch.

Micrometer adalah alat ukur yang paling tepat digunakan untuk mengukur diameter luar piston. Micrometer memiliki tingkat ketelitian yang tinggi dan dapat memberikan hasil pengukuran yang akurat. Dengan menggunakan micrometer, kita dapat mengukur diameter luar piston dengan presisi yang tinggi sehingga mendapatkan hasil yang akurat.

The correct answer is 0,5 mm because it is the only value that is consistent with the given options. The other options are either in centimeters or in millimeters, but only 0,5 mm matches the given units.

The ratchet should be rotated in order to prevent damage to the micrometer when the micrometer spindle touches the surface being measured.

Setiap kali putaran penuh 3600 pada skala timble micrometer menunjukkan gerakan sepanjang adalah 0,5 mm. This means that for every full rotation of 3600 on the micrometer thimble scale, the movement along the scale is 0.5 mm.

The correct answer is "skala sleeve." The micrometer consists of two main scales - the sleeve scale and the thimble scale. The sleeve scale is the larger scale on the outer sleeve of the micrometer. It is used to measure the whole units or millimeters. The thimble scale, on the other hand, is the smaller scale on the rotating thimble. It is used to measure the fractions of a millimeter or tenths of a millimeter. Therefore, the sleeve scale is the main scale or primary scale used in a micrometer.

The commonly found precision values on a caliper / sliding gauge measuring instrument are 0.02 mm and 0.05 mm.

The question describes a vernier caliper with a precision of 0.05 mm. It states that the vernier scale is aligned with the main scale at the 0 mark. The correct answer, 10.0 mm, means that the measurement is 10 mm on the main scale and there is no additional measurement on the vernier scale. This indicates that the measurement is exactly at the 10 mm mark, resulting in a total measurement of 10.0 mm.

The correct answer is 50 - 75 mm because the piston Astrea Supra over size 75 needs to be measured within the range of 50 - 75 mm. This means that the micrometer should have a measuring range that includes this specific range in order to accurately measure the piston. Micrometers with a range of 0 - 25 mm, 25 - 50 mm, and 75 - 100 mm would not be suitable for measuring the piston in this case.

The correct answer is rod 50 mm, washer 3 mm + 1 mm because the final measurement of the cylinder diameter is 53.54 mm. This means that the rod and washer combination should have a total thickness of 53.54 mm. The rod has a thickness of 50 mm, and the washer should have a thickness of 3 mm + 1 mm, which equals 4 mm. So, the total thickness of the rod and washer combination is 50 mm + 4 mm = 54 mm, which is close to the final measurement of 53.54 mm.

The most appropriate use of a caliper based on its accuracy is in measuring the thickness of a clutch lining. Calipers are commonly used to measure small dimensions with high precision, and measuring the thickness of a clutch lining requires such precision. Measuring the diameter of a cylinder, the free play of a brake pedal, or the outer diameter of a piston may also require a caliper, but these measurements may not require the same level of accuracy as measuring the thickness of a clutch lining.

Dial gauge atau jam pengukur dapat digunakan untuk mengukur kerataan permukaan bidang datar, mengukur kerataan serta kebulatan sebuah poros, dan kerataan permukaan dinding silinder. Namun, dial gauge tidak dapat digunakan untuk mengukur diameter luar suatu poros.

The correct answer is "Keausan lebih kecil". This means that the wear on that particular part is less compared to the other positions. The movement of the indicator needle to the right indicates that there is less wear on that specific area of the cylinder.
