Re: PTU B.Tech Syllabus Mechanical

As you are looking for the B.Tech Mechanical Engineering 3rd and 4th semester syllabus of Punjab Technical University (PTU) so here I am providing you.

3rd Sem Syllabus of B.Tech Mechanical of PTU

Unit –I Simple, Compound Stresses and Strains:
Stress and Strain and their types, Hook’s law, longitudinal and lateral strain, Poisson’s ratio, stress-strain diagram for ductile and brittle materials, extension of a bar due to without and with self weight, bar of uniform strength, stress in a bar, elastic constants and their significance, relation between elastic constants, Young’s modulus of elasticity, modulus of rigidity and bulk modulus. Temperature stress and strain calculation due to axial load and variation of temperature in single and compound bars. Two dimensional stress system, stress at a point on a plane, principal stresses and principal planes, Mohr’s circle of stress ellipse of stress and their applications. Generalized Hook's law, principal stresses related to principal strains.

Unit –II Bending Moment (B.M) and Shear Force (S.F) Diagrams:
S.F and B.M definitions; relation between load, shear force and bending moment; B.M and S.F diagrams for cantilevers, simply supported beams with or without overhangs, and calculation of maximum B.M and S.F and the point of contra flexure under the following loads:
a) Concentrated loads
b) Uniformity distributed loads over the whole span or part of span
c) Combination of concentrated and uniformly distributed load
d) Uniformly varying loads
e) Application of moments


Unit –III Bending Stresses In Beams:
Assumptions in the simple bending theory; derivation of formula and its application to beams of rectangular, circular and channel, I and T- sections. Combined direct and bending stresses in afore-mentioned sections, composite / flitched beams. Unit –IV Torsion: Derivation of torsion equation and its assumptions and its application to the hollow and solid circular shafts. Torsional rigidity, combined torsion and bending of circular shafts; principal stress and maximum shear stresses under combined loading of bending and torsion.
