Chapter 8, Problem 1A

To determine

The dimensions A as per the given design of machine.

Answer to Problem 1A

  $A=1\frac{7}{8}\text{ inches}\text{.}$

Explanation of Solution

Given information:

A stamped sheet steel plate is given as shown below. All dimensions are in inches.

Calculation:

Design of machine is shown as below.

From above design we can find the dimensions A as below.

  $\begin{array}{l}A=6\times \frac{5}{16}\\ \Rightarrow A=3\times \cancel{2}\times \frac{5}{\cancel{2}\times 8}\\ \Rightarrow A=\frac{15}{8}\\ \Rightarrow A=1\frac{7}{8}\end{array}$

Thus, dimension of $A$ is $1\frac{7}{8}$ inches.
