1. Hydrostatic Pressure (10 pts)
Gate AB in the figure is a quarter circle (radius: R, width: w into the paper) and hinged at B. This gate holds the water
(density: �) on its right side. Find the force F just sufficient to keep the gate from opening. The gate is uniform and weighs
Mg. The gravitational acceleration is g.
A. Calculate the horizontal component of the press
Problem 1 (20pt) Draw both polar plot and bode plot of the following transfer function:
G(s) = 1
s(s + 1) (1)
Solution of Problem 1 (20pt)
1. (5pt) Consider
G(jω) = 1
jω(jω + 1) (2)
2. (5pt) The magnitude and phase are obtained for ω ≥ 0 as follow:
|G(jω)| =
1
ω
√
1 + ω2
→ |G(jω)|dB = −20 log10 ω − 20 log10
p
1 + ω2 (3)
∠G(jω) = −90◦ W
FPSO라고 들어보셨나요?FPSO의 의미는 영어의 약자 그대로 심해 유전지역에서 물 위에 떠서(Floating, 부유식), 원유를 추출하고 끌어올려(Production), 배 밑의 거대한 탱크에 저장했다가(Storage), 셔틀탱커와 같은 운반선을 통해 저장한 기름을 건네주는(Offloading) 역할을 하는 선박 형태의 설비입니다.

FADE IN:
Credits run in counterpoint through a 7 to 10 minute sequence of
documentary images setting the tone of John F. Kennedys Presidency and
