3. Bosh harakat yuritmasining kinematik strukturasini tahlil qiling. Bunda:







- yuritmaning kinematik strukturasini tashkil etuvchi uzatmalar guruhini aniqlang;

• 
  guruhlardagi uzatmalarning uzatish nisbatini va ularning har bir guruhlardagi munosabatini aniqlang;
  
• 
  chastotalarning geometrik qatori maxrajini aniqlang;
  
• 
  yuritmaning konstruktiv tartibini va guruh xarakteristikasini ko‘rsatish bilan struktura formulasini yozing;
