In the first case A man is in a rased platform, he has a mass of 50kg, h's directly pulling a block of mass 25 kg, the floor below him can witstand a force of 700N, in the second case the smae man pulls the same block on the same platform have ing same withstand capacity of 700N, calculate the force exerted on the floor in both the cases and say which method is better.
Now, obviously the second case is the best,
But I can't seem to arrange each of the components in the formula
Netforce = Resuiltant - Weight ( for first case that is )
And for second case I compared it to a normal object falling down connected to a pulley in which the rope in the other side is connected to a less massive object, but I'm not sure...
The correct answers are
first case force on floor = 750N
second case force on floor = 250N
PLEASE HELP!, I don't want to know what the right anser is , I wANT to know the concept of this question properly....
