Homework Statement
A round bar .125mm in diameter , is to be used as a beam. IF Youngs modulus For the material E=200x103N/mm2 and the stress due to bending is limited to 17.5N/mm2
A) Maximum allowable bending moment
B) the radius of curvature at the point of Maximum bending moment
Homework Equations
σ/y=m/i=E/R
Ina=πD4/64
The Attempt at a Solution
A) 17.5/(125/2)=M/1.1x107 Bending moment =3080000
Ina=1.1x107
B) 17.5/125/2=7/25
=> R= 7/25/200x103 R=1.4mm
