- Q2A sample of wire has a Young modulus E. A second sample of wire made from an identical material has three times the length and half the diameter of the first sample. What is the Young modulus of the second sample of wire in terms of E?E12E0.25E6E30s
- Q3A steel wire has a cross-sectional area 0.5 mm2. The Young modulus of steel is 2.0 × 1011 Pa. Assume the wire obeys Hooke’s law. What load must be suspended from the wire to produce an extension which is 0.1% of the original length?50N40N200N100N30s
- Q4A wire of length L and cross-sectional area A is stretched a distance e by a tensile force. The Young modulus of the material of the wire is E. Which expression gives the elastic energy stored in the stretched wire?BDCA30s
