Sir For this question what do we cos or sin
The length of the fixed link of a crank and slotted lever mechanism is 275 mm and that of the crank 110 mm. Determine, (i) the inclination of the slotted lever with the vertical in the extreme position. (ii) the ratio of the time of cutting stroke to the time of return stroke and (iii) the length of the stroke, if the length of the slotted lever is 495 mm and the line of stroke passes through the extreme positions of the free end of the lever

@@Praveendangeti draw figure...you will automatically understand...or mail me this query

[@Praveendangeti]

@@GAGANBANSAL can you tell me directly which sign will use for 1) inclination of the slotted lever with vertical in extreme position 2) for the length of the stroke
Please I have exam in 1 hour I was little bit hurry

Yes ...trying to improve

[@mrnishan4342]

Where is B

[@GAGANBANSAL]

B is a fixed point on the crank ie a point on the circumstance of the crank circle...it's two extreme positions are B1 and B2... As such B is not shown in the figure...
