Example 3 - 9702/12/M/J/20: An elastic cord of unstretched total length 16.0 cm and cross-sectional area 2.0 × 10^-6 m^2 is held horizontally by two smooth pins a distance 8.0 cm apart.
The cord obeys Hooke’s law. A load of mass 0.40 kg is suspended centrally on the cord. The
angle between the two sides of the cord supporting the load is 60°.
What is the Young modulus of the cord material? #9702s20p12 #ASdeformationP1 #ASforcesP1 #Lv3
