Agata [3.3K]

We have that the  workdone in stretching natural length to is mathematically given as

W=9/2lbft

<h3>Workdone in stretching natural length</h3>

Question Parameters:

  • A force of 128 lb is required to hold a spring stretched 2 ft <em>beyond </em>its natural length.
  • Stretching it from its natural length to 9 inches beyond its natural length

Generally the Hookes equation for the Force   is mathematically given as

F=Kx

Where

3.2lb=2ft*k

Thereofore

k=16

Force becomes

f=kx

f=16x

Hence

W=8[x^2]^{3/4}_{0}

W=9/2lbft
