It collides elastically with smooth horizontal surface after falling. Elongation is a measure of deformation that occurs before a material eventually breaks when subjected to a tensile load. As the latter is applied, an increase in length and a uniform reduction in cross-sectional area take place, while the material maintains a constant volume. Elongation due to expansion can also occur when a material undergoes. Q. A uniform rod of mass m and length L is hinged at one end and free to rotate in the horizontal plane.

Feb 24, 2020 · The impact of a ball with a rigid rod is a standard textbook problem with several surprises. δ = P L A E = σ L E. To use this formula, the load must be axial, the bar must have a uniform cross-sectional area, and the stress must not exceed the proportional limit. If however, the cross-sectional area is not uniform, the axial deformation can be determined by considering a differential length and applying integration. δ = P E ∫ 0 L.
