Calculator 
Definition 
Hollow Structural Section (HSS) Design for Strength

This calculator has been developed to calculate normal stress, shear stress and Von Mises stress on a given cross section of a HSS. 
I Beam Design for Strength

This calculator has been developed to calculate normal stress, shear stress and Von Mises stress on a given cross section of a structural I Beam. 
Linear Thermal Expansion Calculator

This calculator
has been designed to
calculate linear thermal expansion of an unrestrained bar when the temperature of the
bar is uniformly increased or decreased. 
Rectangular Beam Design for Strength

This calculator has been developed to calculate normal stress, shear stress and Von Mises stress on a given cross section of a rectangular solid beam. Calculator also draws graphics of the stress variations with respect to distance from the neutral axis. 
Stresses in Rotating Rings (Annular Disks)

This calculator
has been developed to calculate radial / tangential stresses
(inertia stresses), the change of the inner and outer radiuses of
a ring which rotates about its own axis with a uniform angular velocity. 
Tensile Stress in a Bar

This calculator
has been designed to
calculate tensile stress (or compressive stress),
normal/shear stress on any oblique section of the bar, longitudinal/lateral strain, longitudinal/lateral deflection and total strain energy. 
Thermal Stress in a Bar

This calculator
has been designed to
calculate thermal stress of a restrained bar when the temperature of the bar is uniformly increased or decreased. 
Thermal Stress in a Unifrom Plate

This calculator
has been designed to
calculate stress of a restrained uniform plate when the temperature of the plate is uniformly changed. 
Torsional Stress Calculator of Shafts

This calculator
has been designed to
calculate shear stress, angle of twist, polar moment of inertia of a shaft under torsional loading. Calculator is only valid for solid and hollow
circular shafts. 
SUPPLEMENTS 
Torsion Of Solid Shaft Example

An example about the calculation of torsional stress on stepped shaft. After
calculation of torsional stress, principal stresses are calculated and
evaluation of yield criteria of material is done with these stresses. 
Timber Beam Design for Strength Example

An example about the calculation of normal and shear stresses on timber beam.
