As an example , a cantilever beam was optimized for individual minimum overhang angles , illustrating that overhang angle and gradient constraint need to be concurrently changed and that the compliance is significantly increased over the unconstrained pendant , especially for increased overhang angles .
 material: As; machine or equipment: cantilever beam; process parameter: minimum overhang angles; process parameter: overhang angle; material: be; process parameter: overhang angles
