$3.(4$ points$)$ Anthropometry and Work Place Design

a$.$ Design a fully adjustable workstation for males performing an inspection tasks on catfish fillets. There is not sufficient room to provide a chair. The population for persons performing this task is male between $25$th and $75$th percentile. The work should be set at the elbow. Show all of your work and state all of your assumptions.

$($assumptions: heels $=0\mathrm{.}5",$

$",$ fillet thickness is negligible$)$

b$.$ Design a fixed work surface standing workstation with adjustable platform to fit most females between the $5$th and $95$th percentile. They are performing an inspection task on boxes $7$ tall. The work should be set at waist height

$($assumption: heel $=0\mathrm{.}5")$
