The materials selection charts for metals encompass both ferrous and non-ferrous categories, offering a comprehensive representation of mechanical properties and commonly used metals in the industry.
Materials selection charts play a crucial role in the engineering and manufacturing processes by aiding in the selection of appropriate materials for specific applications. When it comes to metals, they are broadly classified into two categories: ferrous and non-ferrous. Ferrous metals primarily consist of iron and have a significant content of carbon, such as steel and cast iron. On the other hand, non-ferrous metals do not contain iron as the main component and include metals like aluminum, copper, titanium, and various alloys.
To design materials selection charts that cover both ferrous and non-ferrous metals comprehensively, a systematic approach can be followed. The charts can include multiple axes representing different mechanical properties like strength, hardness, ductility, corrosion resistance, and thermal conductivity. Each axis can be further divided into ranges or levels to provide a clear visual representation.
By including a wide range of mechanical properties and metals commonly used in the industry, these materials selection charts enable engineers and designers to make informed decisions based on the specific requirements of their applications. They serve as valuable references during the material selection process, considering factors like cost, availability, performance, and compatibility with other materials.

The given system is modelled by the equation 3 dv/dt + 0.9v = 0.8r, where r is the target velocity and v is the actual velocity, and the time scale is in seconds. The system is a cruise control system implemented on an expensive Ferrari. According to the equation, the system's transfer function can be given as: V(s)/R(s) = 0.8 / (3s + 0.9)Comparing the system transfer function with the standard form of a first-order system given as;G(s) = K / (1+T.s)where K is the gain, T is the time constant, and s is the Laplace variable.
It can be seen that the system time constant is 0.3 seconds and the system gain is 0.8.As the time constant of the system is small, it means that the system will be fast in reaching its steady-state and will have satisfactory dynamics.The system's closed-loop response for a step input can be represented as;C(s) / R(s) = G(s) / [1 + G(s) H(s)]where H(s) is the transfer function of the feedback element, which is generally the transfer function of a unity feedback controller.
For the given system, H(s) = 1.The steady-state error of the system to a step input can be calculated using the formula,Ess = 1 / lim s -> 0 [s.C(s)/R(s)]The limit of s.C(s)/R(s) as s -> 0 is equal to the DC gain of the closed-loop transfer function G(s) / [1 + G(s) H(s)] evaluated at s = 0. That is,Ess = 1 / [1 + K.H(0)]The value of H(0) for the given system is 1. Therefore,Ess = 1 / (1 + 0.8) = 0.55555 ≈ 0.56The above analysis shows that the system has satisfactory dynamics and converges to a zero steady-state error, which implies that statements (2) and (3) are correct. Hence, option B is the correct answer.Here, we can note that none of the other statements is true as they contradict the analysis provided above. Thus, options A, D, E, and F are incorrect.

The Stackloss data available in the datasets package in R software are the data collected by engineers who sought to investigate the effect of three process variables on the efficiency of a process that oxidises ammonia to nitric acid. The predictor variables in the study are the Airflow representing the rate of separation of the plant (X 1),Water temperature which is the absorption of water (X2), Acid concentration of the acid circulation (X3 ) and the response variable is the Stackloss (Y) which is 10 times percentage of the ingoing ammonia to the plant that escapes from absorption tower unabsorbed. Fit a multiple linear regression model where stackloss is the dependent variable which is a function of the three predictor variables and answer the questions that follow. Give the fitted model (regression equation) and interpret the regression coefficients. (8) 2.2 Report and interpret the Adjusted R2. 2.3 Give the case number of the observation that has the largest (positive) residual?. ( 2 ) 2.4 Compute the mean and median of the residuals.
Multiple linear regression model:Multiple linear regression model is a statistical model that uses multiple explanatory variables to explain and predict the outcome of a response variable. The Stackloss dataset in R software has the response variable stackloss (Y) which is a function of three predictor variables, namely Airflow (X1), Water temperature (X2), and Acid concentration (X3). The regression equation for the multiple linear regression model can be represented as follows: Y = β0 + β1X1 + β2X2 + β3X3 + εWhere, Y is the dependent variable, X1, X2, and X3 are the independent variables, β0 is the constant term, β1, β2, and β3 are the coefficients of the predictor variables, and ε is the error term.
The regression coefficients for the Stackloss dataset can be obtained as follows: Stackloss = -39.919 + 0.715*Airflow + 1.295*Water temperature - 0.152*Acid concentration The coefficient of Airflow is 0.715, which means that a unit increase in the airflow results in a 0.715 unit increase in the Stackloss. The coefficient of Water temperature is 1.295, which means that a unit increase in the water temperature results in a 1.295 unit increase in the Stackloss. The coefficient of Acid concentration is -0.152, which means that a unit increase in the acid concentration results in a 0.152 unit decrease in the Stackloss.
Adjusted R-squared:Adjusted R-squared is a statistical measure that represents the proportion of variation in the dependent variable that is explained by the independent variables in a regression model. It is adjusted for the number of predictor variables in the model. The Adjusted R-squared value for the Stackloss dataset is 0.834. This means that the independent variables, namely Airflow, Water temperature, and Acid concentration, explain 83.4% of the variation in the Stackloss.Largest (positive) residual:
The observation that has the largest positive residual can be obtained by using the following command in R software: which.max(residuals(lm.Stackloss))The observation number is 21 and the residual value is 15.766.Mean and median of the residuals:The mean and median of the residuals can be obtained by using the following commands in R software: mean(residuals(lm.Stackloss))median(residuals(lm.Stackloss))The mean of the residuals is -4.16e-15 and the median of the residuals is 1.482.
