Solid Mechanics
- Stress and Strain
- Tension = Positive
- Compression = Negative
- Stress
- Normal Stress=Force/Area
- Stress=Youngs Modulus.Strain
- Strain=change in length/original length
- Elongation=Force.length/Area.E
- DisplacementB=DisplacementA+ElongationAB
- Torsion
- Shear Stress
- Shear Stress for a circle(MAx)=16T/piD^3
- Shear Stress (Max)=Tr/Ip
- Total angle twist=TL/GIp
- Angle = Torque.Length/Shear Modulus of elasticity.Moment of Inertia
- Ip=piD^4/32
- Beam Bending and Moment of Inertia
- I=bh^3/12
- Stress=Mmax.C/I
- Stress=Max moment.Centroid/Inertia
