Locus - Problems on Fork & Slider, Oscillating Link, and Rotating Link
Problems on Fork & Slider, Oscillating Link, and Rotating Link Fork & Slider 6 ] Two points A and B are 100 mm apart. There is a point P, moving in a plane such that the difference of its distances from A and B always remains constant and equals to 40 mm. Draw locus of point P. Solution Steps: Mark the lowermost position of M on the extension of AB by taking distance MN ( 40 mm ) from point B ( because N can not go beyond B ). Divide line ( M initial and M lowermost ) into eight to ten parts and mark them M 1 , M 2 , M 3 , up to the last position of M. Now take MN ( 40 mm ) as fixed distance in compass, M 1 center cut line CB in N 1 . Mark point P 1 on M 1 N 1 with the same distance of MP from M 1 . Similarly locate M 2 P 2, M 3 P 3 , M 4 P 4 , and join all P points. It will be the locus of P. Oscillating Link 7 ] A line OA, 80 mm long oscillates around O, 60ยบ to the right side, and returns to its initial vertical position with uniform velocity. Meanwh...
