The Engineering Design Process

Identify the problem

We have to build barbells for the MEH PE. The barbells are not like normal barbells that have large weights on the ends. We have to build a barbell that is one weighed pole with no weights on the ends.

Criteria and Constraints

• Must be sturdy• Must be safe• Try to reduce as

much cost as possible• Try to use recycled

materials• PVC pipe and other

materials were donated.

Possible solutions/ideasWe were originally going to have a PVC pipe connecting two milk jugs. However this didn’t work, as an interview with the P.E. teacher revealed that we couldn’t do that. So we…

MATERIALS

Reflection

• The barbells might come in handy in P.E. • They can be used differently. You can twirl these

around, for instance.• They also have nice, comfortable grips.• They are pretty sturdy, so they will not break if

dropped.
