Question

(g) The relationship of the applied force F and the displacement x of a spring has the gen eral form F = kx, where the constant k is called the spring constant and is a measure of the stiffness of the spring. Notice that this equation has the form of a straight line. Find the value of the spring constant k of the spring used in determining the experi- mental data plotted in the Fig. 1.6 graph. (Note: Because k Flx, the units of k in the graph are N/m.)

    Hooke’s Law states that the force required to maintain a spring stretched x units beyond its natural length is proportional to x, i.e. f(x) = kx where k is a positive constant. Suppose that 4 J of work is needed to stretch a spring from its natural length 10 cm to a length of 36 cm. Find the exact value of work needed to stretch the spring from 15 cm to 28 cm.
