Chapter 5, Problem 4CP

I am trying to code in MATLAB the equations of motion for malankovich orbitlal elements. But, I am having a problem with the B matrix. Since f matrix is 7x1 and a_d matrix has to be 3x1, the B matrix has to be 7x3. I don't know how that is possible. Can you break down the B matrix for me and let me know what size it is?

I am trying to code the solution to the problem in the image in MATLAB. I wanted to know what is the milankovich constraint equation that is talked about in part b.

Air modeled as an ideal gas enters an insulated compressor at a temperature of 300 K and 100 kPa, and leaves at 600 kPa. The mass flowrate of air entering the compressor is 50 kg/hr, and the power consumed by the compressor is 3 kW. (Rair = 0.287 kJ/kg-K, k = 1.4, cp = 1.0045 kJ/kg-K, cv = 0.718 kJ/kg-K)  Determine the isentropic exit temperature (Te,s) of the air in [K].                  Determine the actual exit temperature (Te) of the air in [K].                           Determine the isentropic efficiency of the compressor. (Answer: ηc,s = 93.3%)                               Determine the rate of entropy generated through the compressor in [kW/K]. (Answer: Ṡgen = 0.000397 kW/K)

A metal plate of thickness 200 mm with thermal diffusivity 5.6 x10-6 m²/s and thermal conductivity 20 W/mK is initially at a uniform temperature of 325°C. Suddenly, the 2 sides of the plate are exposed to a coolant at 15°C for which the convection heat transfer coefficient is 100 W/m²K. Determine temperatures at the surface of the plate after 3 min using (a) Lumped system analysis (b) Analytical one term approximation (c) One dimensional Semi infinite solid Analyze and discuss the results

Problem 3 This problem maps back to learning objectives 1-4 & 8. Consider the particle attached to a spring shown below. The particle has a mass m and the spring has a spring constant k. The mass-spring system makes an angle of 0 with respect to the vertical and the distance between point 0 and the particle can be defined as r. The spring is unstretched when r = l. Ꮎ g m a) How many degrees of freedom is this system and what are they? b) Derive the equation(s) of motion that govern the movement of this system.
