Answer #1

The work that was done to compress the spring will be stored as potential energy in the spring. Now we know that the potential energy stored is given as , where is the distance by which the spring is compressed. So now work done on the spring ,

.( As here ,K= 24 lbs/ft , 1 J=0.738 ft- lb ) .

Hence the work done = 432 J = 318.627 ft-lb.

05.3 Consider a spring that does not obey Hooke's law very faithfully. One end of the spring is fixed. To keep the spring stretched or compressed an amount x, a force along the x-axis with xcomponent Fx =kx – bx2 + cx3 must be applied to the free end, where k = 130 N/m, b = 660 N/m2 , and c = 16000 N/m3 . Note that x > 0 when the spring is stretched and x < 0 when...
