True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?
mmetri Each part has a constant thickness with values indicated. 2.0 mm 1.5 mm 3.0 mm 2.0 mm A shear force, S₂ is applied. This results in shear flow, shown with red arrows, which has the following values: • Shear flow in part 13, just before point 3 - 38 N/mm Shear flow in part 23, just before point 3 = 44 N/mm Shear flow in part 43, just before point 3- 44 N/mm What is the shear stress in part 35, just below point 3? Express your answer in MPa, to 2 decimal places but without the units included. You have a 3% margin of error.
