Greg · Answer 1 · 2022-10-19T19:53:09+0000

Correct answer is (a) 450mm

To explain I would say: We know that length of stroke is:

2x450xsin(90-α/2)

α=120 degrees,

therefore

length = 450mm.

Find the length of stroke if the length of the slotted bar is 0.45m and LOS passes through the free end of the lever. Length of driving crank = 0.12m, distance between fixe centres = 0.24m. Crank and slotted lever quick return motion mechanism.
