A 155 mm projectile is red from a tube with a 1 in 20 twist. Its muzzle velocity is 1000m/s.
What is the spin rate at the muzzle in Hz?
Answer: 322.6 [Hz]
Problem 7
It is requested that a brass slip ring be constructed for a spin test xture to allow elec-
trical signals to be passed (although real noisy) to some instrumentation. The design
requirements are for the ring to have an ID of 4 in., a length of 2 in., and be capable of
