Chapter 81, Problem 1A

To determine

Holes locations by using incremental positioning.

Answer to Problem 1A

The coordinates of holes 1 to 6 are $\left(-15,-10\right)$, $\left(15,-10\right)$, $\left(15,10\right)$, $\left(30,20\right)$, $\left(51.5,30\right)$ and $\left(51.5,20\right)$.

Explanation of Solution

Given:

The holes are shown below:

  

Calculation:

  

Coordinates of the holes byincremental positioningcan calculate from the above figure as follows:

Coordinate of hole 1 is $\left(-15,-10\right)$.

Coordinate of hole 2 is $\left(15,-10\right)$.

Coordinate of hole 3 is $\left(15,10\right)$.

Coordinate of hole 4 is $\left(30,20\right)$.

Coordinate of hole 5 is $\left(51.5,30\right)$.

Coordinate of hole 6 is $\left(51.5,20\right)$.

Thus, the coordinates of holes 1 to 6 are $\left(-15,-10\right)$, $\left(15,-10\right)$, $\left(15,10\right)$, $\left(30,20\right)$, $\left(51.5,30\right)$ and $\left(51.5,20\right)$.

Conclusion:

The coordinates of holes 1 to 6 are $\left(-15,-10\right)$, $\left(15,-10\right)$, $\left(15,10\right)$, $\left(30,20\right)$, $\left(51.5,30\right)$ and $\left(51.5,20\right)$.
