Figure$1.$ Multi$-$rotor system

In the given multi$-$rotor system, with the provided values $m1=4kg,m2=4kg,r1=50mm,r2=74mm,z1=95mm,z2=430mm,1=$

$127,2=249,LR=600mm,$ and the presence of $2kg$ masses available for balancing the multi$-$rotor shaft, the following

questions arise:

a$-)$ Where should the $2kg$ mass be placed in the $R$ plane? In other words, at what radius should this mass be positioned in the

R plane? $($mm$)$

b$-)$ Where should the $2kg$ mass be placed in the R plane? In other words, at what angle should this mass be positioned in the

R plane? $($degrees$)$

c$-)$ Where should the $2kg$ mass be placed in the L plane? In other words, at what radius should this mass be positioned in the

L plane? $($mm$)$

d$-)$ Where should the $2kg$ mass be placed in the L plane? In other words, at what angle should this mass be positioned in the $L$

plane? $($degrees$)$
