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 
@@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
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...
Sir aap bhut aacha se samjhaye hai ❤❤
Thanks dear Manish 👍👍🎉

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

@@Praveendangeti q= 21.8 degree
@@Praveendangeti length of slotted bar =296.18 mm
@@Praveendangeti now calculate directly the length of stroke
How do we know should we know cos should we use cos or sin
It depends on configuration
Nice explanation sir... thank you 👌👍
Thanks dear sanket
thanks sir on solving
Stay productive...
Tq sir😊
U r always welcome
Vd quality is very low 😢
Yes ...trying to improve
Where is B
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...
Thank you sir you are best
