Question

The formula T=11.0/d+0.320 gives the number of threads per inch in a standard machine screw which is d inches in diameter. Find the approximate value of T when d= .178 inch???

Answer 1

The formula \(T=\dfrac{11.0}{d+0.320}\) gives the number of threads per inch in a standard machine screw which is d inches in diameter.
Find the approximate value of T when d= .178 inch.

Step 1: Input known values:
\(T=\dfrac{11.0}{.178+0.320}\)
Step 2: Simplify:
\(T=\dfrac{11.0}{0.498}\)
Step 3: Simplify even more:
\(T = 22.0884\)

Here is a neat tip:
Try crossing out unneeded information in word problems:
The formula \(T=\dfrac{11.0}{d+0.320}\) \(\cancel{\text{gives the number of threads per inch in a standard machine screw which is d inches in diameter.}}\)
Find the approximate value of T when d= .178 inch.
