Solution
Cos = 0 = 900SolutionThe problem has two conceptual answers13.9 and 9013.9 is the only realistic answerAt = 90, the moment arm will interfere with the rest of the assemblyPhysical ModelBuilt model has different dimensions than the book problem and thus a different solution
Physical Model
Physical Materials5 pound weightWood obtained from a barnCabinet handlesSpringRopeSteel pipeBall bearing pulley
Angle Measurement - TRIZNeeded a way to measure the equilibrium anglePrinciple of Add another dimensionAdded a protractor and measurement device

Mechanism AnalysisPro/ Engineer has countless applicationsOur team decided to use the Mechanism Application to conduct a Static Analysis to solve our problem
Virtual SolutionFirst, the a snapshot of the initial condition was taken
Virtual Solution ContinuedNext, a Spring with a Spring Constant of 101.0967 lbf/ft is defined. The Unstretched length of the spring is to be defined as the length when the moment arm is parallel with the base
Virtual Solution ContinuedA force of 5 lb is then defined at the weight
Virtual Solution ContinuedThe virtual model will under go a static analysis
The Solution found using Pro/ Engineer:After running a static analysis we will measure the angle. We received an angle of 8.53
