You are designing a pair of pliers based on the size of
your hand
a) Measure the breadth of your hand
3.6 inches = 9.15 cm = 0.0915 m
b) Determine how many standard deviations your hand
breadth size is away from the average, using the anthropometry
table in the Anthropometry slides
Hand breadth (inches) - 5th percentile: 3.1; 50th percentile:
3.5; 95th percentile: 3.9; 1 standard deviation: 0.2
Z=(X-μ)/σ ; X=3.6 inches ; μ=3.5 inches ; σ=0.2
Z=(3.6-3.5)/0.2 --> Z=0.5
c) Assuming your hand is the smallest (if less than
average) or largest (if larger than average) for the design
population, determine the range of hand breadths that can use your
pliers using a symmetrical standard deviation from
average.
d) Using your hand breadth, determine the largest force
your pliers can exert on an object if a = 3*b = 9 cm, and you exert
a 200 N force on the pliers
