Applicable Problem

• Aerospace Engineers of the Boeing aircraft must add the weight of the engines, fuel, passengers, cargo, and frame of the plane when programming the planes intelligent system to sense safe take off weights. Afterwards, the engineers want to build a plane with a frame made of materials with nano-tubes to determine how many more passengers, how much more cargo, or how much more fuel the plane can carry.

Boeing 717 Specs

• take off weight = 110,000 lbs = t• engine = 18,500 lbs = e• fuel = 24,609 lbs = f• passengers = 13,250 lbs = p• cargo = 13,250 lbs = c• plane frame = ? = pf

Inequalitye + f + p + c + pf < t

Weight of Frame

• What is the maximum that the frame of the plane can weigh?

e + f + p + c + pf < t

(18500 + 24609 + 13250 + 13250) + pf < 110000

69609 + p < 110000 -69609 - 69609 p < 40391

The Plane frame can weigh up to 40,391lbs

Nano-materials and a New Plane Frame• What would be the new weight of a plane

frame built with nano-materials, if nano-materials decrease the original weight of the plane frame by 1/6?

Old Plane Frame – (1/6)Old Plane Frame = New Plane Frame

40391 – 6731.833 = 33659.167

More Luggage

• How much cargo (luggage) can the passengers bring on the plane with a frame made of nano-materials.

e + f + p + c + pf < t 18500 + 24609 + 13250 + C + 33659.167 < 110000

90018.167 + c < 110000 -90018.167 -90018.167 c < 19981.833

Boeing 747 Specs

• take off weight = 875,000 lbs = t• engine = 184,900 lbs = e• fuel = 334,632 lbs = f• passengers = 78,600 lbs = p• cargo = 52,400 lbs = c• plane frame = ? = pf

INDEPENDENT PRACTICE

• What is the maximum that the plane frame can weigh?

• What would be the new weight of a plane frame built with nano-materials, if nano-materials decrease the original weight of the plane frame by 1/5?

• How much cargo (luggage) can the passengers bring on the plane with a frame made of nano-materials.

Notes: Force ( N ) = mass (kg) x acceleration (m/s) gravity (g) = 9.80 m/s21 kg = 2.205 lbs1 ft = 0.3048 m

• What is the mass of the airplane in kilograms if it weighed 700lbs.

• Calculate the force on the plane.

Cont.

• Calculate the speed in f/s if the plane flew 122 feet in 11 seconds. Then draw a distance time graph.

• Convert this speed to

meters/second.
