A certain part of an aircraft engine has a volume of 1.6 ft^3
A. Find the weight of the piece, when it is made of brass.
B. If the same piece is made of aluminum, what is its weight ?
C. Determine how much weight is saved by using aluminum instead of brass
. (please show the step used to get these answers)
Homework Answers
a)density if brass = 8.5 gm/cc
so the volume will have a weight of 8.5 *1.6*30.48^3 / 1000 = 385.11 kg.
b) density of aluminium = 2.7 gm /cc
so the volume will have a weight of 2.7 *1.6*30.48^3 / 1000 = 122.33 kg.
c) 262.78 kg of wt is saved by using aluminum instead of brass

Problem 3 - Quarterly demand of a spare part for a certain aircraft engine during the last two years (in sequence) is 250, 200, 180, 190, 225, 285, 305, and 190. Determine the forecasts for periods 3 to 9 using 2 period moving averages (MA-2) and Exponential smoothing with α = 0.2 and α = 0.4 (i.e. ES (0.2) and ES (0.4)). For ES (0.2) and ES (0.4) calculations, assume that the forecast for period 2 was 250. Compare MAD,...
