Hello, in this question we have a uniform rod, let us say a uniform piece of medical apparatus and the weight of it is given to be 1 ,200 newton and it is suspended horizontally using two wires.
00:21
So let us say two wires a and b are used to suspend this medical apparatus horizontally.
00:28
The length of this medical apparatus is 3 .5 meter.
00:33
Now there's another small mass of 550 newton that is placed on this medical apparatus at a distance 2 meter from the end.
00:43
From the end b.
00:45
So now the question asked is what would you find the tension in the wire a and the wire b? so now first thing that we need to understand here is the system isn't equilibrium.
01:00
What type of equilibrium it is? it is in translatory as well as rotational equilibrium.
01:06
Neither the system is rotating, neither the system is translating.
01:11
That means all vertical forces acting on the system is equal to the downward forces acting on the system.
01:19
So let us say the tension in this wire is t -a and the tension in this wire is t -d.
01:26
That means i can write down the equilibrium equation.
01:30
T a plus tb should be equal to the net weight acting in the downward direction, that is 550 plus 1 ,200.
01:41
So that would give you 1 ,750 newton.
01:46
This is the first equation...
