A spring with a 2-kg mass and a damping constant 1 can be held stretched 1 meters beyond its natural length by a force of 5 newtons. Suppose the spring is stretched 2 meters beyond its natural length and then released with zero velocity, In the notation of the text, what is the value c² - 4mk? in meters, after t seconds. Your answer should be a function of the variable t with the general form c₁eat cos(ẞt) + c₂e" sin(St) m2kg/sec² Find the position of the mass, α = B = γ y = 8 = C₁ = C₂ =

1) During a particular manufacturing process a hoop of mass m and radius r is to roll without slip on a slant before getting to the next step in the assembly line. The floor manager has approached you and wants to know what the minimum coefficient of friction would have to be to prevent the hoop from slipping. a) Explicitly define coordinates for the inclined plane and write out the corresponding transformation array. b) Draw an FBD and IRD for the system. c) Compute the coefficient of friction required to ensure the hoop does not slip if B = 45°. [Ans. to Check: µ = 0.5] m

I’m making the graph that you see in the picture but the code that I’m using makes the line with to many curves. Could you make the lines look like the one that you see on the graph. Don’t change the color just make it with a little bit less curves like you see in the picture. Use this code on MATLAB and fix it. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Fix the random seed for reproducibility rng(50); % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Combined best fit combinedFit = (fitDiesel + fitPetrol) / 2;…

Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…
