Which lathe specification directly affects tool life, machining accuracy, and workpiece surface finish

2.1) The support reactions are calculated now: \(A_{x} = 10\,kN\), \(A_{y} = -10\,kN\), \(B_{y} = 30\,kN\).

2.2) The member CD is on tensile load and the member BC is on compressive load. \(F_{BC} \approx 28.284\,kN\), \(F_{CD} = 20\,kN\)

The dynamic situation of a mechanical system whose geometry cannot be neglected is described by Newton's laws and D'Alembert's principle. A planar system in equilibrium is described by the following formulae:

\(\sum F_{x} = 0\)     (1)

\(\sum F_{y} = 0\)     (2)

\(\sum M = 0\)     (3)

2.1) The support reactions can be found by assuming that the truss is a rigid solid:

\(\sum F_{x} = A_{x} - F = 0\)    (4)

\(A_{x} = F\)

\(A_{x} = 10\,kN\)

\(\sum M_{A} = F\cdot r_{BD} - G \cdot (r_{AB}+r_{CD}) + B_{y}\cdot r_{AB} = 0\)     (5)

\(B_{y} = \frac{G\cdot (r_{AB}+r_{CD})-F\cdot r_{BD}}{r_{AB}}\)

\(B_{y} =\frac{(20\,kN)\cdot (8\,m)-(10\,kN)\cdot (4\,m)}{4 \,m}\)

\(B_{y} = 30\,kN\)

\(\sum F_{y} = A_{y} + B_{y} - G = 0\)     (6)

\(A_{y} = G - B_{y}\)

\(A_{y} = 20\,kN - 30\,kN\)

\(A_{y} = -10\,kN\)

Note - The negative sign means that the real direction of the component is antiparallel to the assumed one.

2.2) If the entire system is at equilibrium, then every part of the system must be also at equilibrium. The joint is considered a particle and thus the D'Alembert's principle is not necessary. The member CD is on tensile load and the member BC is on compressive load.

\(\sum F_{x} = F_{BC} \cdot \cos 45^{\circ} - F_{CD} = 0\)     (7)

\(\sum F_{y} = -G + F_{BC}\cdot \sin 45^{\circ} = 0\)     (8)

By (8):

\(F_{BC} = \frac{G}{\sin 45^{\circ}}\)

\(F_{BC} \approx 28.284\,kN\)

By (7):

\(F_{CD} = F_{BC}\cdot \cos 45^{\circ}\)

\(F_{CD} = 20\,kN\)

When designing a set of simple test programs to determine the type compatibility rules of a C compiler to which you have access, it is important to consider the different data types that are used in C programming. An example of a set of test programs that can be used to determine the type compatibility rules of a C compiler:

Integer Test the compatibility of the C compiler with integer data types. It declares two variables of type int, initializes them with values, and then adds them together. The result is printed to the screen. If the program compiles and runs without any errors, then the C compiler is compatible with integer data types.

Floating-Point Test  the compatibility of the C compiler with floating-point data types. It declares two variables of type float, initializes them with values, and then adds them together. The result is printed to the screen. If the program compiles and runs without any errors, then the C compiler is compatible with floating-point data types.

By running the set of simple test programs described above, you can determine the type compatibility rules of a C compiler to which you have access.

Two kg of a two phase liquid vapor mixture of carbon dioxide (CO₂) exists at -40°C in a 0.05m³ tank. Determine the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor CO₂ at -40°C are \(v_{f}\) = 0.896 x 10⁻³m³/kg and \(v_{g}=\) 3.824 x 10⁻²m³/kg, respectively.

Answer: x = 1

Explanation: In a phase change of a pure substance, at determined pressure and temperature, the substance exists in two different phases: saturated liquid and saturated vapor.

Quality (x) is the ratio of saturated vapor in the mixture and can be written as:

\(x=\frac{m_{vapor}}{m_{liquid}+m_{vapor}}\)

It has value between 0 and 1: x = 0 for saturated liquid and x = 1 for saturated vapor.

When related with volumes, quality is rearranged as:

\(x=\frac{v-v_{f}}{v_{g}-v_{f}}\)

Solving for x:

\(x=\frac{0.05-0.896.10^{-3}}{3.824.10^{-2}-0.896.10^{-3}}\)

\(x=\frac{0.049104}{0.037344}\)

x = 1.3

Quality of mixture of carbon dioxide is x = 1, which means it's for saturated vapor.

Computational multi-phase convective conjugate heat transfer on overlapping meshes can be effectively addressed using a quasi-direct coupling approach via the Schwarz alternating method.

The blue print drawing of the house shows 666 centimeters, but the real picture of the house is 333 meters. So let the number of cm on the blueprint that represent the distance of 272727 meters be x. Firstly convert the meters to centimeters 666cm = 333m, x=272727m ; then cross multiply, 666cm=33300cm x=27272700cm ; x =(666cm×272727cm)/33300cm =545454cm.

The closed-loop system exhibits different stability characteristics for different values of the proportional control gain K. For K = 19, the system is overdamped. For K = 116, the system is critically damped. For K = 100, the system is underdamped.

The closed-loop system is controlled by a proportional controller with gain K, aiming to regulate the angular position of a heavy object to a desired position. The transfer function T(s) relates the output o(s) to the input ;(s) and is given as T(s) = 1 + KG(s), where G(s) = 1/(s(s+20)).

1. The Laplace transform of the output o(s) is determined by multiplying the transfer function T(s) with the input ;(s). Given that the input ;(t) is a unit step function, the Laplace transform of o(t) is o(s) = T(s)U(s), where U(s) is the Laplace transform of the unit step function.

2. For K = 19:

(i) The system is overdamped, which means that it exhibits slow but stable response without oscillations.

(ii) By substituting the values of K and G(s) into the expression for o(s), and applying inverse Laplace transform, we can find o(t). By utilizing MATLAB functions like subplot and plot, the plot of o(t) can be generated.

(iii) The convergence of o(t) can be analyzed by observing its behavior over time. As an overdamped system, o(t) should reach its desired position without any overshoot and settle gradually.

3. For K = 116:

(i) The system is critically damped, implying a fast response without oscillations.

(ii) Similarly, o(t) can be found by substituting K and G(s) into the expression for o(s) and applying inverse Laplace transform. MATLAB functions can be used to plot o(t).

(iii) The convergence of o(t) can be analyzed by observing its behavior. Being critically damped, o(t) should reach its desired position quickly without overshooting.

4. For K = 100:

(i) The system is underdamped, indicating a response with oscillations.

(ii) Following the same procedure as before, o(t) can be determined and plotted using MATLAB.

(iii) The convergence of o(t) can be analyzed by observing its oscillatory behavior. As an underdamped system, o(t) will exhibit oscillations before settling down to the desired position.

Answer:

The greatest mass, that the weight C can have such that block A does not move is approximately 23.259 kg

Explanation:

The given parameters are;

The mass of the block A= 58 kg

The coefficient of static friction between the block and the surface, \(\mu _s\) = 0.300

The coefficient of static friction between the rope and the fixed peg, B \(\mu _B\) = 0.310

Let T represent the tension in the rope

Therefore, when the rope is static, T = The normal reaction at the peg, B, \(N_B\)

The angle of inclination of the rope holding the block A = arctan(3/4) ≈ 36.87°

The length of the rope = √(0.4² + 0.3²) = 0.5

∴ sin(θ) = 3/5 = 0.6

cos(θ) = 4/5 = 0.8

The vertical component of the tension in the rope = T × sin(θ) = 0.6·T

The horizontal component of the tension in the rope = T × cos(θ) = 0.8·T

The friction force = μ×(W - 0.6·T) = 0.300×(58×9.8 - 0.6·T) = 170.52 - 0.18·T

The block will start to move when we have;

The horizontal component of the tension in the rope = The friction force

∴ 0.8·T = 170.52 - 0.18·T

0.8·T + 0.18·T = 170.52

0.98·T = 170.52

T = 170.52/0.98 = 174

Therefore, the tension in the rope = T = 174 N = The normal reaction at the peg, B \(N_B\)

The frictional force at the peg, \(F_B\) = \(\mu _B\) × \(N_B\) = 0.310 × 174 N = 53.94 N

The weight of the mass, \(m_c\), \(W_c\) = The frictional force at the peg, \(F_B\)  + The tension in the rope

∴ The weight of the mass, \(m_c\), \(W_c\) = 53.94 N + 174 N = 227.94 N

Weight, W = Mass, m × The acceleration due to gravity, g, from which we have;

m = W/g

Where;

g = 9.8 m/s²

∴ \(m_c\) = \(W_c\)/g = 227.94 N/(9.8 m/s²) ≈ 23.259 kg.

The greatest mass, that the weight C can have such that block A does not move = \(m_c\) ≈ 23.259 kg.
