If a man is standing on a chair its chances of breaking are more,but if man sits on the chair ,chances o breaking are less.Explain

Answer 1

heya frnd

we know that pressure = force / area

when a man stands on chair , then area of contact will be less . so pressure on chair will be more

as pressure is inversely proportional to area

so there are more chances for breaking of chair

whereas when person sits on chair , area of contact will be more , so pressure acting will be less

so there are less chances for breaking of chair
