A student suspends a spring from a clamp stand. He measures the unstretched length of the spring with no load attached. He then attaches different loads to the lower end of the spring and measures the new lengths of the spring.
Fig. 1.1 shows how the total length of the spring depends on the load attached.
At point P on Fig. 1.1, the line stops being straight and begins to curve.
State the name of point P.
______
Using Fig. 1.1, determine the unstretched length of the spring.
unstretched length = ______
Calculate the extension of the spring for a load of 4.0 N.
extension = ______
