A copper sphere has a radius of 2.50 m under normal room pressure of 1.0  105 N/m2. If we increase the pressure on this sphere to 10 times the normal room pressure, what is the change in its volume? The bulk modulus for copper is 1.4  1011 Pa.
 
  What will be an ideal response?

Question 2

What is the maximum length of a metal cable that can hang vertically supported from one end of the cable?
 
  The Young's modulus of this metal is 2.10  1011 N/m2, its tensile strength (the maximum tensile stress it can support without breaking) is 7.40  108 N/m2, and its density is 7.60  103 kg/m3.
  A) 9.94 km
  B) 4.22 km
  C) 456 km
  D) 1.75 km
  E) 24.8 km
