Mass of each top member Ms = .05 kg
Mass of each bottom member Mbs = .05 kg
Displacement after which the mast is self-deployable Zd = .2 m
Solution:
From equations (3.5) to (3.9)
Number of levels on each side N=2
Number of plates C = 9
Weight of the top member of the strut Wts = .9810 kg
Weight of the plate Wp = 1.962 kg
Total length of strut when deployed Lmax = 1.414 m
3.4.1
From equations (3.13) and (3.14)
Minimum deflection of the springs dmin = .1514 m
Minimum stiffness of spring in level 1 K1 =11 N/m
Minimum stiffness of spring in level 2 K2 = 28.6 N/m
3.4.2
From equations (3.16) to (3.21)
For level 1
Stiffness of the spring K = 12.5 N/m
