Hello, Could you please help with the question attached or give guidance please, thnk you
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 thedriving crank is 126 mm. Find the inclination of the slotted bar with the vertical inthe 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 ofstroke passes through the extreme positions of the free end of the lever.
|design a simple piston-like crank-slider mechanism that looks similar to the Figure 4 (not to scale). The centre of the crank and the slider are aligned vertically to each other. It has already been determined that the crank radius (O2A) must be 25mm, while the slider block is in a square shape of 20 mm by 20 mm. The highest position of the slider (Hmax), which is the furthest vertical distance of the slider from the centre of the crank, must be 92 mm. Based on the given design parameters, your task is to determine the suitable couple length (AB) and the lowest position of the slider (Hmin). Your superior has asked you to present the results graphically. 20 Slider 10 20 H Crank O2 Figure 4
