Mobiles -- Blend of Physics and Art
Mobile Construction -- Torque Assessment
Alexander Calder
Received a degree in mechanical engineering but soon after decided to pursue a career as an artist.

Constellation & Tower
Mobile Supported by Stabile
Authentic Assessment
Students apply the concepts learned in the unit • Torque• Balance• Center of Mass• Pivot
Project Details Project counts as an exam Design plan must accompany mobile
• Diagram of mobile showing locations of weights for each tier
• Torque calculations for each tier• Mobile itself
Mobile Requirements Your mobile should have a theme
• For example, a mobile with an astronomical theme would contain stars, planets, comets, etc.
Each mobile must contain 5 tiers At least 1 tier must contain 3 masses At least 2 tiers must be pivoted from a
point other than the cg of the support rod
You must include a layout of the mobile design
Design Layout for Each Tier
the mass of the support rod the masses of the hanging ornaments the lengths of the respective lever arms the location of the pivot Mathematical proof that the torques are
balanced
Design Plan
If the mass of your support rod is significant compared to the masses of your hanging ornaments, be sure to include the torque exerted by the weight of the support rod in your calculations.
Mobile Grading Scheme
25 pts. for your design plan 25 pts. for the 5 tiers -- 5 pts. for each tier 5 pts. for one tier containing 3 masses 10 pts. for two tiers pivoted at point other
than cg of support rod 10 pts. for proper balance -- i.e. horizontal
orientation of supports
Grading Scheme Continued
10 pts. for theme 15 pts. for artistic design and aesthetic
value BONUS: 5 pts. bonus for science theme BONUS: 5 pts. bonus for extra tier
100 pts. total
