IDE 20 Engineering Design w/Computer Applications
Project (FS10) -- Kinetic Battery
Project Description
Your team is tasked with building a system that stores energy from a fixed source
(the tower) and then supplies this energy to move a ballistic pendulum (the
hammer).
Rules
•
No net external energy may be used, all energy must originate with the
energy stored in the tower
•
All aspects of your team’s design must be safe, and will be audited by your
instructors
•
The device does not need to be automated, external control can be used
•
During testing, no team member (or proxy) may be closer than 24″ to the
testing area
•
Your team’s device may not be in physical contact with the hammer until
activated after the 10s storage period
Specifications
•
The tower will store approximately 50J (reduced from 100J) of energy (5kg
weight elevated slightly higher than 1m)
•
The hammer will store approximately 50J of energy when pushed back (or
pulled) 90 degrees from rest
•
Your team has a volume 48″ long, 20″ wide and 60″ tall to work with
•
A basic anchoring system is provided consisting of 1/2″ holes drilled every 4″
in the members connecting the hammer and tower
Testing Sequence
•
Your team’s device is weighed, placed in test area and anchored
•
The tower weight is raised and secured
•
Your team’s device is connected to the tower
•
All team members leave the test area
•
The tower weight is released
•
Once the weight has stopped moving, a timer is started
•
After at least 10s, your team’s device is activated
•
After activation, your team’s device pushes (or pulls) the hammer
•
Once the hammer comes to rest, the maximum energy storage will be
recorded
•
You team removes your device and another team begins testing
Grading
A minimally functioning device meets all competition rules and has stored at least
2J of energy in the hammer during one of the formal testing periods. A minimally
functioning device will be awarded a grade of 70%. Grades between 70% and
100% will be awarded based on a linear weighting of figure of merit from lowest to
highest. The figure or merit will be calculated as follows:
FoM=1.0*E-0.5*m
•
E: Energy stored in hammer (Joules)
•
m: mass of teams device (kg)
