ENGG1010 Foundations of Engineering Mechanics Examination: Dec 14, 2010, 9:30am-12:30pm, Flora Ho Sports Centre Exam paper is divided into Sections A and B, each containing 3 questions. You are required to attempt 5 out of the 6 questions . Section B – two questions on fluid mechanics (Take g = 9.81 m/s 2 , density of water = 1,000 kg/m 3 ) Pressure Absolute and gauge pressure. Hydrostatic pressure variation with depth: ( ) below above or is vertical depth below free surf ace p gz p p g z z ρ ρ = Δ = Manometer and differential manometer: ( ) / 1 m m p gh ρ ρ ρ Δ = Hydrostatics Hydrostatic pressure distribution on the surface of a submerged body. Formulas to calculate the magnitude and depth of centre of pressure for the resultant force acting on a submerged plane surface: ( ) 2 3 sin , , for rectangular surfa 2 ce 1 g R c R c g c I bd F gh A h h I h A θ ρ = = + = The center of a trapezoidal distribution is at a distance from one end of the distribution given by h 2 3( ) a b h a b + + b a Second moment of area (formulas except for a rectangular area need not be remembered).
