In the given question we are told that a package is on a ramp that is inclined at an angle of 36 degrees to the horizontal and we are told that to prevent the package from sliding a force of 105 newton is required.
00:16
So what we are first asked to find is we have to find the magnitude of the force c of the package against the ramp.
00:25
So in the question, a few other things are given to us.
00:31
These two forces are given like this.
00:34
And there is a force that is given to us.
00:40
Let's just draw it like this.
00:42
So these two are two forces.
00:46
And there is a force directly vertically down.
00:49
There is a force marked like this.
00:52
And this is c.
00:54
This is labeled c in the figure this is labeled g in the figure this is labeled q and this is labeled p what we can see over here is that according to the question we were told that to prevent the package from sliding a force of 105 newton is required right so to prevent the package from sliding q would be the force that helps this process right to stop the package from sliding so this means we can take q as 105 newton and now we don't know what the value of p is but what we could do is we could resolve the vertical force over here which is g into its components so what we would have then is we would have a force like this and we would have a force which is like this right so these are the components of the force g and what we could see is that the angle which is over here would be over here in this case 36 degrees and we can say that this over here is over here is this over here is g cosh 35 degrees and this over here is g sine 35 degrees right so what we could do then is we have just found what forces are c and p.
02:32
P and c are actually the components of the force, vertical force, g.
02:38
So we can just write that over here...
