  1. September 22, 2011 IOTPOLYENGINEERING I1-12 • DRILL: NEATLY DEFINE … • MEGABYTE • NANOMETER • MICROGRAM • KILOCALORIE

  2. Answers to today’s Drill IOTPOLYENGINEERING I1-12 • DRILL: NEATLY LETTER THE DEFINITION OF … • MEGABYTE - 106bytes • NANOMETER - 10-9meter • MICROGRAM - 10-6 gram • KILOCALORIE - 103 calorie

  3. IOTPOLYENGINEERING I1-12 • SUMMARY OF THE 7 FUNDAMENTAL SI UNITS: • LENGTH - meter • MASS - kilogram • TIME - second • ELECTRIC CURRENT - ampere • THERMODYNAMIC TEMPERATURE - Kelvin • AMOUNT OF MATTER - mole • LUMINOUS INTENSITY - candela

  4. IOTPOLYENGINEERING I1-12 meter, kilogram, second, Kelvin, etc. THE INTERNATIONAL SI SYSTEM OF MEASUREMENT IS COMPRISED OF 7 FUNDAMENTAL (OR BASE) QUANTITIES. THE ENGLISH SYSTEM, USED IN THE UNITED STATES, HAS SIMILARITIES AND THERE ARE CONVERSION FACTORS WHEN NECESSARY. foot, pound, second, Fahrenheit, etc.

  5. DERIVED UNITS IOTPOLYENGINEERING I1-12 • Combine Base Units to Make New Units • Area = Length x Length • Speed = Length / Time • Density = Mass/Volume = Mass / (Length3) • Force = Mass x Acceleration • = Mass x Length/Time2

  6. Space Worksheet IOTPOLYENGINEERING I1-12 1) How much time does it take for sunlight to reach Earth 150 million km 103m s 150 x 106 km x x 1 km 3 x 108m 1 min 500 s x = 8.3 min 60 s

  7. Space Worksheet IOTPOLYENGINEERING I1-12 7) How long would it take to travel the shortest distance from Earth to Mars if the spacecraft at 18,000 km/hr? Distance from sun to Mars 228 x 106 km Distance from sun to Earth 150 x 106 km Distance from Earth to Mars 78 x 106 km 1hr 1 day 78 x 106 km x x 180 days 18000 km 24 hrs

  8. Space Worksheet IOTPOLYENGINEERING I1-12 7) How long would it take to travel the shortest distance from Earth to Mars if the spacecraft at 18,000 km/hr? Distance from sun to Mars 228 x 106 km Distance from sun to Earth 150 x 106 km Distance from Earth to Mars 78 x 106 km 1hr 1 day 78 x 106 km x x 180 days 18000 km 24 hrs

  9. Space Worksheet IOTPOLYENGINEERING I1-12 9) If a softball represents the Sun, what diameter sphere would represent the Earth? Sun is softball = 4 inches Let Earth diameter = x Sun’s diameter= 1,392,000 km Earth’s diameter = 12,756 x 12,756km = 4 in 1,392,000km x= 0.037 in

  10. Space Worksheet IOTPOLYENGINEERING I1-12 9) If a softball represents the Sun, what diameter sphere would represent the Earth? Sun is softball = 4 inches Let Earth diameter = x Sun’s diameter= 1,392,000 km Earth’s diameter = 12,756 x 12,756km = 4 in 1,392,000km x= 0.037 in

  11. Conversions IOTPOLYENGINEERING I1-12 Convert 2 miles to meters Convert 10 ns to ms Convert 10 g/cm to kg/Mm Convert 5.2 J/L to kJ/mL
