MULTIPLE-BAR MECHANISM FOR DRAWING CISSOIDS

Click to enlargeClick to enlarge Description

The lengths of the links comply with the conditions: B͞C=B͞E, D͞C=C͞K=K͞E=E͞D and A͞B=A͞D. Thus links 2, 3, 4, 5, 6 and 7 constitute an inversor. When link 1 turns about fixed axis A, point K describes a cissoid with the polar equation ρ=(a+2ksin²(ϕ))/(cos(ϕ)) where a is the value of radius vector ρ when ϕ=0, and ϕ is the angle of rotation of radius vector ρ.
