1. what is the total length of this link?

5/8 r
typ
3 1/2
?
4 3/4
5 1/8
3 1/2
4 1/8

Explanation:

Step1: Identify given values

The distance between the centers of the two holes is $3\frac{1}{2}$, and the radius of each rounded end (TYP, typical) is $\frac{5}{8}$. Since there are two rounded ends, their total contribution is $2\times\frac{5}{8}$.

Step2: Convert mixed number to fraction

$3\frac{1}{2} = \frac{7}{2}$

Step3: Calculate total length

Add the distance between centers and the total length of the two rounded ends:

$$ \frac{7}{2} + 2\times\frac{5}{8} = \frac{7}{2} + \frac{10}{8} = \frac{28}{8} + \frac{10}{8} = \frac{38}{8} = 4\frac{6}{8} = 4\frac{3}{4} $$

Answer:

4 3/4
