Hi, in this question we have a camshaft.
00:03
So, camshaft with 25 revolutions.
00:07
So, revolutions per second.
00:12
So, that means for one second there is so for one second there is 25 revolutions.
00:19
So, now we can write for 0 .7 seconds.
00:23
So, one second implies 25 revolutions.
00:27
So, for 0 .75 seconds we have so it is 25 into 0 .75 which is equal to so it is 18 .75 revolutions.
00:38
Now, we have to so let us draw the shaft.
00:42
So, let us have the spherical shaft.
00:44
So, this is a spherical shaft camshaft.
00:50
So, with the center of the camshaft is at the origin.
00:54
So, let this be center and this be the four quadrants.
00:58
So, four quadrants and this be the center now.
01:03
So, now let us mark the point xy.
01:05
So, x comma y is the point which is according to the question it is...
