2.  Armament (weapons): None  Engines: Two Pratt and Whitney J58’s (each weighing 6,000 lbs.)  Maximum Speed: Mach 3.2 (3.2 times the speed of sound)  Range (how far it can go on one tank of fuel): 2,900 miles  Ceiling (how high the plane can go): 85,000 ft.  Wingspan: 55ft 7in  Length:107ft 5in  Height: 18ft 6in  Weight (empty): 67,500 lbs  Weight (loaded):170,000 lbs  First flown: 1964  Number built: 32  Wing Area: 1,795 ft. sq. each 3590 ft. sq. total  Thrust (in lbs.): 32,500 lbs per engine 65,000 lbs total

3.  Pressure in Pounds per Square Inch  Force in lbs. of thrust  Area as in area of the wing ft. sq.  PSI= 65,000 lbs. /3,590 ft. sq.  Have to change 3,590 ft. sq. into 516,960 in. sq. by multiplying 3,590 ∗ 12²  PSI=65,000 lbs./ 516,960 in. sq.  PSI=0.126

4.  P ∗ A = F  P ∗ A/A F/A  P= F/A  Pressure = Force/Area
