Question

5. 1. The wearing parts of a coal mining machine are made of hardened tool steel, but are rarely, if ever, lubricated. The left and right wear plates for a typical tracked vehicle measure 60" long by 12" wide, and each tests at 360 HB. The vehicle weighs 12 tons. How far can it travel underground before each wear plate is reduced in thickness by 1/8"? Give the answer in miles. Steel Tracks Wear Plate

Step 1

The wear plate is reduced in thickness by 1/8", which is equal to 1/8/12 = 1/96 feet. Since the wear plate measures 60" long, the initial thickness is 60/12 = 5 feet. Show more…
