1)A 24-m long metal wire (cross-section 1.1 cm2,
Young's modulus
1.8 ´ 1011 N/m2), is subjected
to a load of 24 kN. How much will the wire stretch under the load?
(write your answer in cm)
2)How large a force is necessary to stretch a 1.2-mm diameter
metal wire (Y =
11´ 1010 N/m2) by 1.7 % of its
original length?
