To make a plot of hardness vs. % reduction in thickness, assuming that % reduction varies linearly across the width of the specimen from 0 at the edge to 50% at the center, follow the steps below:
Step 1: Take a specimen whose width is 50 mm. The reduction varies linearly across the width of the specimen from 0 at the edge to 50% at the center. Therefore, the reduction at a distance x from the edge is given by the equation: Percent reduction (ε) = 50 - (2 * x)
Step 2: From the given data, we know that hardness is directly proportional to the percent reduction in thickness. Therefore, we can write the hardness (H) as:Hardness (H) = k x Percent reduction (ε)where k is the constant of proportionality.
Step 3: Substitute the value of percent reduction (ε) in the above equation to get:Hardness (H) = k x (50 - 2x)
Step 4: Simplify the above equation to get it in the form of y = mx + c, where y is the dependent variable (hardness), x is the independent variable (% reduction in thickness), m is the slope of the line, and c is the y-intercept.Hardness (H) = -2kx + 50k
Step 5: Now we can plot the graph of hardness vs. % reduction in thickness using the equation derived in step 4. The graph will be a straight line passing through the point (0, 50k) and having a slope of -2k. The x-axis represents the % reduction in thickness, and the y-axis represents the hardness.
The graph will look like this: Hardness vs. % reduction in thickness plot

Understanding the demographics of an audience is crucial because it helps the speaker tailor their message to meet the specific needs and interests of different groups. By adapting their approach accordingly, speakers can improve the effectiveness and impact of their communication.
It matters that an audience may be composed of different demographic groups because the characteristics of the audience can influence the effectiveness of communication and the reception of the message. Understanding the composition of the audience allows the speaker to tailor their message to resonate with their specific needs, interests, and cultural backgrounds. Recognizing the diversity within the audience helps to avoid assumptions, stereotypes, or biases that may hinder effective communication. It allows the speaker to adapt their language, examples, and delivery style to connect with the audience on a deeper level. For example, if the audience is predominantly older people, the speaker may choose to use more relatable references from their generation or adjust the pace and volume of their speech to accommodate potential hearing impairments.
