Question

a) A truck (X) carries 100 kg of iron bars while another identical truck (Y) carries 100 kg of wheat. Which of the two is likely to be more stable and why?​

Answer 1

Answer:

Let us take, the normal

reaction extorted by

man on the load be 'N'

since, the load has downward acceleration of 'g'

Applying Newton's II law of motion (F

net

=ma)

⇒10g−N=10×g

⇒N=0

Since, the normal reaction on the load is zero

⇒ the man will experience no weight of

the load i.e. zero weight.

Answer 2

Answer:

IRON TRUCK WILL BE MORE STABLE COMPARE TO COTTON.

Explanation:

1. BECAUSE THE LOAD OF IRON WOULD HAVE A MUCH LOWER COG AS COMPARE TO COTTON LOAD MAKING IT MORE STABLE .

2. AS COTTON HAS LOWER DENSITY OCCUPY MORE VOLUME THIS MAKES COTTON LOAD TRUCK C.O.M TO BE FURTHER GROUND MAKING LESS STABLE .
