QuestionCalculate the usable tread depth of a tire if new depth is 9.94 mm9.94 \mathrm{~mm} and worn out depth is 1.59 mm1.59 \mathrm{~mm}.

Studdy Solution

STEP 1

Assumptions1. The tread depth of the tire when new is9.94 mm. The tread depth at which the tire is considered worn out is1.59 mm3. The usable tread depth is calculated by subtracting the worn out tread depth from the new tread depth

STEP 2

We need to find the usable tread depth of the tire. We can do this by subtracting the tread depth at which the tire is considered worn out from the tread depth of the tire when new.
Usable tread depth=New tread depth−Worn out tread depthUsable\, tread\, depth = New\, tread\, depth - Worn\, out\, tread\, depth

STEP 3

Now, plug in the given values for the new tread depth and worn out tread depth to calculate the usable tread depth.
Usable tread depth=9.94 mm−1.59 mmUsable\, tread\, depth =9.94\, mm -1.59\, mm

STEP 4

Calculate the usable tread depth.
Usable tread depth=9.94 mm−1.59 mm=8.35 mmUsable\, tread\, depth =9.94\, mm -1.59\, mm =8.35\, mmThe tire's usable tread depth is8.35 mm.
