Hello there,

How have you been? Here is our next part for your preparation of GATE and PSUs examinations.

All information is learned through books and practical exercises.

- A T-section is used as a simply supported beam with uniform loading. The maximum bending stress for a given load will occur at the bottom of the section.
- Mohr's circle becomes zero when the both the axial stresses are equal in magnitude and of same nature and both planes being free from shear.
- For beams, I-sections are more economical than rectangular sections because most of the material is concentrated away from the centroid.
- The shear stress distribution over a rectangular cross section of a beam follows a parabolic path.
- Shear stress distribution diagram varies for different cross sectional shapes.
- Bending stress distribution diagram is similar for different sections.
- Polar moment of inertia is sum of MI about the XX and YY axes.
- A cantilever beam of uniform EI has span equal to 'L'. An upward force W acts at the mid point of the beam and a downward force P acts at the free end. In order that the deflection at the free end is zero, the relation between P and W should be W=16P/5.
- If K is defined as the ratio of Young's modulus of elasticity and the permissible stress in compression of a material used in the construction of a column, then the Rankine's constant used in finding the load carrying capacity of columns is proportional to 1/K.
