Question

if a man stands on a chair ,chances of its breaking are more but if a man sits on a chair, chance s of its breaking are less.explain

Answer 1

Answer:

Explanation:

if a man stands on a chair ,chances of its breaking are more but if a man sits on a chair, chances of its breaking are less because as man sits the mass is distributed and pressure becomes low . pressure=mass/area

Answer 2

Answer:

Because of the area.

Explanation:

If a man stands on the chair, his whole body weight acts downward, on the chair.

Since,

Pressure=Force/Area,

The pressure increases when the area decreases which explains why standing on a chair exerts more pressure on the chair, causing it to break. When you sit, the area in contact with the seat is more, so pressure decreases. Thus the chair does not break.
