Problem 4.30 While the stiffness of an elastic cord can be quite constant (i.e., the force versus displace- ment curve is a straight line) over a large range of stretch, as a bungee cord is stretched, it softens; that is, the cord tends to get less stiff as it gets longer. Assuming a soften- ing force-displacement relation of the form k8 - B83, where 8 (measured in ft) is the displacement of the cord from its unstretched length, considering a bungee cord whose unstretched length is 150 ft, and letting k = 2.58 lb/ft, determine the value of the con- stant B such that a bungee jumper weighing 170 lb and starting from rest gets to the bottom of a 400 ft tower with zero speed.

A steel panel is subjected to a compressive loading in order to improve the panel stiffness and to increase its buckling strength. It is swaged with the swage depth of 13 mm and swage angle of 60.07°. Its profile is as shown in Fig.Q2. Typical dimensions are shown in the figure and the thickness of the panel is 0.8 mm. The effective length of the panel is 750 mm. The relevant properties are: Modulus of elasticity Yield stress 200 GN/m? 240 MN/m? . Assuming that the buckling stress coefficient for a panel simply supported on both sides is 3.62 and that the post buckling relationship for the panel is Oy = 0.40, +0.60, where oav = average panel stress, o, = edge stress in panel and o = panel buckling stress, determine (a) the load/swage pitch at which initial buckling of the panel will ccur, (b) the instability load per swage pitch.
