Given parameters:
- Length of slotted bar (L1) = 150 cm
- Length of crank (L2) = 50 cm
- Length of connecting rod (L3) = 75 cm
Formula:
Stroke length = 2*(L2 + L3 - sqrt(L3^2 - L1^2))
Calculation:
- L2 + L3 = 50 + 75 = 125 cm
- L3^2 - L1^2 = 75^2 - 150^2 = -11250 (negative value, indicating an imaginary number)
- sqrt(L3^2 - L1^2) = sqrt(-11250) = imaginary number
- Thus, stroke length = 2*(125 - imaginary number) = 2*(125 - i*sqrt(11250)) = 2*(125 - i*75*sqrt(2))
- Simplifying, stroke length = 2*(125 - 106.07i) = 2*(125 - 106.07) = 37.86 cm (approx)
Therefore, the stroke length of the crank and slotted lever quick return motion mechanism is approximately 200 cm (option B).
