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 and
respectively. The respective masses of disk 1 and disk 2 are denoted
and
. The elastic spring is connected to both disks at radius,
. Disk 1 has a radius of
and disk 2 a radius of
. 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 en
. Die massas van skyf 1 en skyf 2 word telkens deur die simbole
en
verskaf. Die elastiese veer is verbind aan albei skywe by 'n radius van
. Skyf 1 het 'n radius van
en skyf 2 het 'n radius van
. 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, .
Calculate the value of .
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, .
Bereken die waarde van .
