Read DetailsA SPTA is performing a MMT with a patient in the sitting position. For shoulder flexion, the patient has 100 degrees of PROM, and 0 degrees of AROM. In the gravity eliminated position the individual is able to move ~ 20 degrees. Which of the following BEST describes the MMT score for this patient?
Read DetailsConsider the converging-diverging duct that is shown (not to scale). The following parameters are known: = 86 kPa, = 220 K, = 0.78, = 0.4 m2, = 3.5 kPa. Find: Also find the stagnation pressure and stagnation temperature. (a) The exit cross-sectional area. Answer: [A2] m2 (round to one decimal place) (b) The exit Mach number. Answer: [M2] (round to two decimal places) (c) The stagnation temperature in the duct. Answer: [T0] K (round to one decimal place) (d) The stagnation pressure inside the duct. Answer: [P0] kPa (round to one decimal place)
Read DetailsA nozzle duct is placed in a room at standard conditions. Some of the exit conditions are known: = 0.24, = 280 K, and = 1 m2. A differential pressure gauge -as shown- is measuring the difference in pressure between the inlet and exit to be 3.721 kPa. Find: (a) The inlet’s cross-sectional area. Answer: [A1] m2 (round to one decimal place) (b) The Mach number at the inlet. Answer: [M1] (round to two decimal places)
Read DetailsConsider the 2-D wedge-shaped vehicle shown. The vehicle has a mass of 9000 kg, and its engine (not shown) provides 70 kN of thrust. The vehicle is in level (constant-altitude) flight. The sides’ lengths, angles, as well as the averaged (uniform) pressures and shear stress magnitudes on the different surfaces are tabulated below. Neglect friction on the leeward side (face ). = 7.732 m
