Hello friends.
00:02
In this question we have two masses that is being pulled by f1 and these are attached these masses are attached by a strain.
00:12
So we have to draw the free body diagram for these masses.
00:16
First i will draw the free body diagram for the m1 mass.
00:22
So it is being pulled by a force air and there will be a resistance in the backward side that will be because of this tension.
00:33
Then this mass will be applied by the force of gravity, so that will be m1g, and there will be reaction from the ground that will be created as normal or reaction n1.
00:46
You can call that n1.
00:48
These are the four forces.
00:50
There is no vertical motion, so this a vertical must be zero, and there can be some forward motion, so this a horizontal will have some value.
01:03
So we will just normally call it 8 for the ease.
01:08
So the first equation will be f minus of some resistance because of this t since it is the opposite direction so there will be negative sign and this will cause the final acceleration of m1a.
01:22
If you are equating the vertical direction that will be we are taking this one, positive y direction as this one...
