A steel bar 2 m long, 40mm wide and 20mm thick is subjected to an axial pull of 160 KN in the direction of its length

A steel bar 2 m long, 40mm wide and 20mm thick is subjected to an axial pull of 160 KN in the direction of its length. Find the change in length, width and thickness of bar. Take E= 200Gpa and Poisson’s ratio= 0.3

Change in length (δl)=PLAE

Given, P=130103N,L=4200mm

W=35mm,t=25mm

E=200GPa,E=200103N/mm2

μ=0.3

δL=130103420035254200)103

δL=1.48mm

PoissonsRatio=LateralstrainLongitudinalstrain

Calculations of changes in width : -

Lateralstrain=δwworδtt

Longitudinalstrain=δLL

μ=δwwδLL

0.3=δw3524200

δW=0.022mm

Calculation of change in …
