So here, all the terms given are, or the terms in the options given are mechanical advantage, effort, load and effort arm, load, so things like that.
00:12
So first thing we would have to do is we have to understand what are all these terms.
00:17
Now, say if we have a mechanical system here, so if we have a mechanical system here like this, and this is the fulcrum here, or this is the supporting point we have here, and if we have a load on if we have a force on this mechanical system and if we have another force here let this be the effort and this be the load why because here we would have to have this effort and load and the effort is the input force on a mechanical system and the load is the output force overcome by the mechanical system.
01:03
Now let this be the load and effort.
01:06
We can write how we think like maybe we can write this effort into opposite direction as well.
01:12
So that doesn't matter.
01:14
Now this distance from load to this fall from here.
01:19
This distance means load arm and this distance and this distance from center to here means effort arm.
01:34
So this is the distance we have here.
01:36
Till here...
