Chapter 3, Problem 3.158RP

While using a pencil sharpener, a student applies the forces and couple shown. (a) Determine the forces exerted at B and C knowing that these forces and the couple are equivalent to a force-couple system at A consisting of the force R = (2.6 lb)i + R_yj – (0.7 lb)k and the couple M A R = M x i + ( 1.0 lb ⋅ ft ) j − ( 0.72 lb ⋅ ft ) k . (b) Find the corresponding values of R_y and M_x.

Question 2 You are an engineer working in the propulsion team for a supersonic civil transport aircraft driven by a turbojet engine, where you have oversight of the design for the engine intake and the exhaust nozzle, indicated in Figure Q2a. The turbojet engine can operate when provided with air flow in the Mach number range, 0.60 to 0.80. You are asked to analyse a condition where the aircraft is flying at 472 m/s at an altitude of 14,000 m. For all parts of the question, you can assume that the flow path of air through the engine has a circular cross section. (a) normal shock 472 m/s A B (b) intake engine altitude: 14,000 m D exhaust nozzle→ exit to atmosphere 472 m/s 50 m/s B diameter: DE = 0.30 m EX diameter: DF = 0.66 m Figure Q2: Propulsion system for a supersonic aircraft. F a) When the aircraft is at an altitude of 14,000 m, use the International Standard Atmosphere in the Module Data Book to state the local air pressure and tempera- ture. Thus show that the aircraft speed of…

given below: A rectangular wing with wing twist yields the spanwise circulation distribution kbV1 roy) = kbv. (2) where k is a constant, b is the span length and V. is the free-stream velocity. The wing has an aspect ratio of 4. For all wing sections, the lift curve slope (ag) is 2 and the zero-lift angle of attack (a=0) is 0. a. Derive expressions for the downwash (w) and induced angle of attack a distributions along the span. b. Derive an expression for the induced drag coefficient. c. Calculate the span efficiency factor. d. Calculate the value of k if the wing has a washout and the difference between the geometric angles of attack of the root (y = 0) and the tip (y = tb/2) is: a(y = 0) a(y = ±b/2) = /18 Hint: Use the coordinate transformation y = cos (0)
