A technician uses a standard vernier caliper with 0.001-inch resolution to measure the outside diameter of a transmission output shaft. On the main beam, the zero mark on the vernier plate has moved past the 2-inch mark, past the major graduation 3 (representing 0.300 inch), and past two 0.025-inch subdivision lines. On the 25-division vernier plate, the line marked 18 aligns precisely with a graduation line on the main beam. What is the total measured diameter of the shaft in inches?
Cevap: 2.368 in
Cevap
The total measured diameter of the transmission output shaft is 2.368 inches.
To read a standard inch vernier caliper, sum the whole inches (), the exposed tenths on the main beam (), the exposed subdivisions (), and the aligning vernier division (). Adding these together gives .
Adım Adım Çözüm
Anahtar Kavram
Reading a 0.001-inch vernier caliper by combining the main beam whole inches, tenths, 0.025-inch subdivisions, and the aligning vernier plate division.
Alternatif Yöntem
Convert each scale value into thousandths of an inch before summing: 2000 thousandths (whole inches) + 300 thousandths (major mark 3) + 50 thousandths (two 0.025-inch increments) + 18 thousandths (vernier alignment) = 2368 thousandths, which equals 2.368 inches.
