Question 1
A dimensioned shaft with basic size and tolerance values per shaft segment is shown in
Figure 1 (Units in mm). There are four shaft segments in total. Determine the following:
1.1
Calculate the cumulative upper tolerance of the entire shaft.
1.2
Calculate the cumulative lower tolerance of the entire shaft.
State the tolerance for the shaft by giving the basic size, upper and
lower limits in an appropriate format.
1.3
Calculate the average fall time and standard deviation using the data above.
Average - 1.5s
Stdev- 1.85s
Use the average fall time and one of the kinematic equations to determine the height of the building.
Add the standard deviation from step 1 to the average fall time from step 2. This represents a “maximum fall time.” Use this time to calculate the “maximum” height of the building.
What's the mean of the following points? x = [-3 3 4 2 -1 1 4 5]
