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

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
