6.1a Ex2 MJ20 P13 Q20 Ratio of Rod Diameter in Building | As Deformation | CAIE A Level 9702 Physics

Example 2 - 9702/13/M/J/20: The diagram shows a simplified model of a building with four identical heavy floors. The spacing of the bottom floor from the ground is twice that of the spacing between the floors. Between each floor are equal numbers of vertical steel supporting rods of negligible mass compared with the floors. The rods are of different diameters so that the stress in each rod is the same. What is the ratio diameter of bottom rods / diameter of top rods? #9702s20p13 #ASdeformationP1 #Lv3 MJ20 Physics Paper 1 Full Discussion Playlist:    • 9702 MJ20 Papers CAIE Physics   AS 9 #DeformationofSolids Playlist    • Ch6 Deformation Solids | CAIE 9702 AS Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
