mass if m = 0.5 kg at a distance of e = 0.15m from the axis of rotation, as shown in Fig.3.55.
The tail section has a length of 4 m, a mass of 240 kg, a flexural stiffness (EI) of 2.5 MN-m2, and a damping ratio of 0.15. The mass of the tail rotor blade, including their drive system, is 20 kg.
Determine the forced response of the tail section then the blades rotate at 1500 rpm.
탈수통의 기울임각과 stiffness
탈수기의 진동을 다루기 위해 탈수통을 바닥에 damper와 spring으로 고정되어 있다고 가정하였다. damper는 회전축과 동일선상에 위치해있고, spring은 탈수기의 중심에서 만큼 떨어진 곳에 위치해있다. 이 때 탈수기의 불평형 질량에 의해 탈수기 전체가 중심축을 기준으로
represents a rotating leader and a core group, making
everyone a leader. Every member will be eager to make opinions,
and are more likely to find better, creative solutions than Kraft food.
§ Also Kraft food may seek for outside advisers like the colleague in
Orpheus group. Creative external advises can be a good guideline
for such a stiff organization like Kraft Food.

A DOZEN NEW RECRUITS step off the plane, unloading their duffel bags, looking around like only the new can look around, their hair regulation-clipped, crisp, new green fatigues fitting them like cardboard.

Catherine and discover a man crouched behind her, kissing her back.
Catherine is standing on a low mechanics platform and her skirt has been raised and hooked over the wings flap. She wears garters and stockings but no panties.
The man, handsome, cruel-looking, rises up behind her, enters her, kisses her neck. Catherine half closes her eyes. She rotates her pelvis gently against his thrusting.
