Question

which of the two balanced forces or unbalanced forces can change the shape of an object give an example of to illustrate your answer

Answer 1

Hiii there
Unbalanced force can change it's shape because body changes it's shape because of stress on it which depends upon pressure and pressure is a scalar quantity, so it adds up to stress irrespective of the direction of force.

In case of net force zero, pressure on the body will add up to apply more stress which will change it's shape.

Answer 2

heya,,
I think unbalanced force have ability to change the shape of object. it is because if the force is more than the the inertia of object then it will be able to change the shape of object.
ex; drawn of wire etc.
