Problem 6: Rubber Band Redux The potential energy of a rubber band of relaxed length L when it is stretched to a length 6' may be shown to be 1 g a 2:2\" where k is a constant. [:1] Calculate the corresponding force (F) as a function of length. (b) Sketch the force versus length. [c] Show that the rubber band obeys Hooke's law for small extensions and determine the corresponding rubber band stiffness. Answer (a) F = gin :) Answer (b) v' LJ (e) Explain why the force curve given by your answer to (a) and sketched in (b) is not in fact applicable to rubber bands under a compressive load. I need to know the answer of E. Would you explain it'?r
