1.	As shown in adjacent figure if a load of mass (m) is attached at lower end of lower wire. Then find the displacements of the points B, C, D are
Answer» SOLUTION : As shown in figure ELONGATION of 1ST wire `e_1 = ((mg)l_1)/(Ay_1)` elongation of 2nd wire `e_2 = ((mg)l_2)/(Ay_2)` elongation of 3RD wire `e_3 = ((mg)l_3)/(Ay_3)` displacement of B is `e_1` displacement of C is `e_1 + e_2` displacement of D is `e_1 + e_2 + e_3`
