from QFD, what factor use to determine most important design specification?

Is it the absolute weight or relative weight? How can I list the order of importance of the design specification using data from QFD?

y'=y-x^2 ; y(1)= -4

My MATLAB program won't work. I am trying to get the main program to output a plot of the three equations (1 from the main program and two called in the function). The goal is to code a Euler method and a 2nd order Taylor numerical solution for

a. x0= 1.0 , step size h= 0.2, # of steps n=20

b. x0= 1.0 , step size h=0.05 , # of steps n=80 ; write a separate functionn for f(x,y) that is called. Plot the results on the same plot as the exact solution.

I keep getting an error of "Matrix Dimensions must agree ; error in Project_2(my function) with my Tay = ... equation (2nd order taylor equation).

Main Code

t_span = 1:0.2:5;
h=0.2;
y1 = -4;
B=(t_span.^2);
[x,y] = ode45(@(x,y) y-x^2, t_span, y1);
d=[x,y];
project_2(y1,h,d,B)

subplot(4,1,1)
plot(x,y)

xlabel('value of x')
ylabel('value of y(x)')
grid on

t_span = [1:0.05:5];
y1 = -4;
h=0.05;
[x,y]= ode45(@(x,y) y-x^2, t_span, y1);
subplot(4,1,4)
project_2(y1,h,d,B)
plot(x,y)
xlabel('value of x')
ylabel('value of y(x)')
grid on

The Function

function [outputArg,Tay] = project_2(y1,h,d,B)

outputArg = y1 + h*d; %Euler method

Tay= y1 +(h*d)+((1/2)*(h^2))*((y1-2*t_span)+(-B)*d); %2nd order Taylor

subplot(4,1,2)
plot(outputArg)

subplot(4,1,3)
plot(Tay)

A piston–cylinder device contains 0.85 kg of refrigerant-134a at -10°C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 88 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 10°C. Determine (a) the final pressure, (b) the change in the volume of the cylinder, and (c) the change in the enthalpy of the refrigerant-134a.

1. The main disadvantage of belts/chains compared to gears is that belts/chains are more likely to transmit noise, shock, and impact than gears are. T/F.

2. A large pulley rotates CCW, meshes with a belt, and the belt meshes with a smaller pulley. The smaller pulley must rotate faster and CCW. T/F.

3. Uniform wear and uniform pressure are simultaneously applied in clutch analysis. T/F.

4. The units on the coefficient of speed fluctuation can be either RPM or rad/sec. T/F.

5. Both clutches and brakes are designed to bring the relative velocity between two mating surfaces to zero. T/F.

Provide an example of steel which has been coated for protection. Explain the coating, fabrication and good and bad points of the coating selection.  

A power train application requires the coupling of a spur gear to a transmission shaft operating at 3600RPM. The coupling must sustain a mean torque loading of 215Nm. There is a 20% torque ripple introduced to the drive line from the load. Select and design a coupling system using either a keyed coupling or an interference coupling such that the section of the transmission shaft at that location is minimized. Assume that the gear is located at the midpoint of the shaft and introduces a steady transverse load of 1000N. The center to center on the bearings is 6.5" (6.5 * 25.4 = 165.1mm)
