The document outlines a team's design project for a prosthetic hand for swimming. The team includes Rajarshi as the design lead, Frank as the analysis lead, Tim as the manager and communication officer, and Sam as the fiscal and testing officer. The design must meet constraints of being lightweight, buoyant, corrosion-resistant, and inexpensive to manufacture. Three potential designs are presented along with design criteria and proposed tests to evaluate speed, ease of use, and buoyancy.

2. Case scenario
These folks with amputated arms love swimming just as much as other swimmers.

4. Constraints and Criteria
Constraints
● Designed for free-style swimming.
● Be around 2.3% of human weight[5].
● Density should be near to water.
● Should not rust or react chemically with salt or
chlorinated water.
● Manufacturing must cost less than $100.
Criteria
● Easy to be installed and uninstalled so that it can
be done by one hand.
● Efficient to use, not waste any power. Should be
curved to a certain degree.
● Should be able to be manufactured easily.
● The contact surface with skin should use elastic
material.
● The forces exerted by each hand on the water
should be equivalent.
