A pin P is confined by a path r = 3 sin(20) feet in a vertical plane and the slotted arm OA. Arm OA is rotating with a constant angular velocity (w) of 0.3 rad/s when 0-25. Complete the highlighted areas: a) Draw the cartesian coordinate (xx). b) Draw the tangent-normal coordinate (t,n). c) Draw the polar coordinate (re). Answer: r = 3 sin(20) feet A are (-1.034,0,694) 0=25
