The diagram shows two thin disks, which are pinned and free to rotate about their geometrical centres. The disks are connected by an elastic spring with a stiffness, k, and rotate without friction through angles theta subscript 1 and theta subscript 2 respectively. The respective masses of disk 1 and disk 2 are denoted m subscript 1 and m subscript 2. The elastic spring is connected to both disks at radius, r. Disk 1 has a radius of r and disk 2 a radius of R. Unless specified otherwise please round off all answers to 2 decimal points and DO NOT include units with your answer.

Die diagram vertoon twee dun skywe, wat vasgepen is en vrylik roteer om hulle geometriese middelpunte. Die skywe is verbind deur 'n elastiese veer met 'n styfheid, k, en hulle roteer sonder wrywing deur hoeke theta subscript 1 en theta subscript 2. Die massas van skyf 1 en skyf 2 word telkens deur die simbole m subscript 1 en m subscript 2 verskaf.  Die elastiese veer is verbind aan albei skywe by 'n radius van r.  Skyf 1 het 'n radius van r en skyf 2 het 'n radius van R. Rond alle antwoorde tot 2 desimale punte af en MOENIE eenhede by u antwoord insluit nie.

Determine the equations of motion for the system, symbolically, in matrix form. First, write the full geometric equations without any assumptions. Make the small-angle assumption only when the equations are written in matrix form.  The system's equation of motion then has a mass matrix of the form, open square brackets table row cell m subscript 11 end cell 0 row 0 cell m subscript 22 end cell end table close square brackets

Calculate the value of m subscript 22

Work with the units as they were provided. 

Use: m1 = 1.6 kg, m2 = 1.5 kg, k = 1.7 N/m, r = 9.6 m, R = 5.8 m

Bepaal die bewegingsvergelykings van die sisteem, simbolies, in matriksvorm. Skryf eers die vergelykings ten volle uit met alle geometriese funksies. Maak eers die klein hoek aanname wanneer u die antwoord in matriksform skryf.

Die bewegingsvergelyking van die sisteem het `n massamatriks in die vorm van, open square brackets table row cell m subscript 11 end cell 0 row 0 cell m subscript 22 end cell end table close square brackets.

Bereken die waarde van m subscript 22

Werk met die gegewe eenhede.

Gebruik: m1 = 1.6 kg, m2 = 1.5 kg, k = 1.7 N/m, r = 9.6 m, R = 5.8 m
