What is the weight of the load and force that our worker exerts on the rope? so this is for the worker.
00:10
This is hand, right? so this is pulled up with the hand, right? now this is rope a, b and c here, right? so we will make a free body diagram.
00:29
So for this, you will make a free body diagram for part one.
00:35
You can say step one, free body diagram would be how much? it would be this much is upward and this much is downwards that is mg and this is equals to 1450 newton and this is the tension t a you can see, right? in this chain a, right? so this would be given by, but this pulley is connected to this one, right? this rope that means t plus t.
01:12
So t plus t would be 2t that would be given by t a would be equals to because t a is acting like this also in this way t a is acting like this.
01:24
So the value of t a would be t a is equals to mg, right? t a would be equals to 2t which is equals to mg you can say and 2t would be equals to 1450, right? and you will be getting 1450, right? so you can say that what it is as weight of the load and the force.
01:55
So weight of the load is 1450 newton, right? this would be the answer, right? now from these two, right? so you have concluded mg is equals to 1450 and mg is nothing but w only, okay? that is the weight, okay? now we got the answer for the first part...
