Question

In a crank and slotted lever quick return motion mechanism shown in Fig. for Q. No.
1(c), the distance between the fixed centers is 224 mm and the length of the
driving crank is 126 mm. Find the inclination of the slotted bar with the vertical in
the extreme position and the time ratio of cutting stroke to the return stroke.
If the length of the slotted bar is 442 mm, find the length of the stroke if the line of
stroke passes through the extreme positions of the free end of the lever.
