Cevap:
12B
13A
Açıklama:
12-) Fk1=Gk
2V.d.g=3V.dk.g
dk= 2d/3 olur.
Fk2= Gtop
3V.d.g= 3V.dk.g+3V.dL.g
3Vdg= 3Vg(dk+dL)
dk+dL= d
2d/3+dL= d
dL= d-2d/3= d/3 olur.
mk/mL= (3V.2d/3)/(3V.d/3)= 2Vd/Vd= 2 olur.
13-) Fk1= Gtop
3V.2d.g= 3Vg(dk+dx)
d+dx= 2d
dx= 2d-d= d olur.
Fk2=Gtop
3V.3d.g= 3Vg(dk+dy)
d+dy= 3d
dy= 3d-d= 2d olur.
mx/my= (3V.d)/(3V.2d)= 1/2 olur.
