MECH $324$

HW$03-$ Position Analysis

Problem $3$: The following image shows a sixbar linkage proposed as a new suspension design.

Calculate the mobility of the mechanism. $(5$ points$)$

Develop systems of equations using vector loop method that represent a mathematical model of the position of this mechanism. Assume all length dimensions are known. $(10$ points$)$

Express how many inputs are needed to render your systems of equations solvable. Clarify which variable you select as input and which variable as solved output. $(5$ points$)$

Write an equation for the position of the point of contact with ground. $(10$ points$)$

$1$ ground

Rubric for the vector loop method:

All lengths and angles are defined with clear symbols in a graphic model. $(4$ points$)$

Vectors are demarcated from scalars using an overhead arrow. $(2$ points$)$

Vector loop is correctly used to derive systems of equations. $(4$ points$)$
