The suspended load exerts a force on the spring and pushes the spring downwards. As a result, the spring gets stretched. Hence, its shape gets changed.But does it not change the weight of the object as now the object's weight would slightly differ because of the gravitational and frictional force acting on it?

Solution

The weight of the object will remain unchanged because it is not a function of friction force. Weight itself is a force which is equal to mass(m) $\times$ gravitational acceleration(g) and since the mass and the gravitational acceleration will remain constant even tough the shape of the spring changes the weight will not change.

NOTE: Weight is the gravitational force that acts on the spring and causes it to change its shape.
