Homework Statement
Your task is to determine:
a.the length and bore of cannon that is required to accommodate an 80 kg Clown with an over-arm measurement of 48 inches
b.the amount of fuel that is required to launch the Clown at the same angle as you did with your model cannon .
c.the amount of fuel that is required to launch the Clown at the same angle as you did with your model cannon onto a foam mattress 30 m away.
Test Cannon
Diameter of Ball: 7cm
Length of Cannon Barrel: 21.5cm
Length of Compression Chamber: 6.5cm
Amount of Fuel Used: 2.6mL of Methanol
Distance Travelled: 1.256m
Life Size Variables
Diameter of Life Sized Clown: 60.96cm
Distance Clown Must Travel: 30m
Mass of Clown: 80kg
Angle: 25°
The Attempt at a Solution
a. (Diameter of Clown/Diameter of Ball)xBore of Model Cannon=Bore of Real Cannon
(62.661cm)
(Bore of Life Sized Cannon/Bore of Model Cannon)xLength of Model Cannon= Barrel length of real cannon (185.653cm)
(length of model compression chamber/length of model barrel)xLength of life sized Cannon Barrel= Compression chamber of life sized cannon (56.122cm)
And I have no idea where to start with the estimating fuel part :(
This is a group project but its due tomorrow and I've been left with trying to finish it all by myself so I really really need help!
