The parallel-link mechanism ABCD is used to transport a component I between manufacturing processes at stations E, F, and G by picking it up at a station when θ = 0 and depositing it at the next station when θ = 180°. Knowing that member BC remains horizontal throughout its motion and that links AB and CD rotate at a constant rate in a vertical plane in such a way that v B = 2.2 ft/s, determine ( a ) the minimum value of the coefficient of static friction between the component and BC if the component is not to slide on BC while being transferred, ( b ) the values of θ for which sliding is impending.
