SALIENT FEATURES OF SPRINGS CLASS NOTES FOR MECHANICAL ENGINEERING Spring is an important part in almost every machinery. These springs perform different functions in different applications. These absorb shocks in vehicles running on uneven roads. These store energy in toys and circuit breakers. These give cushion effect in vehicles. Springs are of different types…
BENDING & AXIAL LOADING COMBINED MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ increases understanding and clarity. Bending and axial loading is equivalent to eccentric loading. Complex stresses produce under bending and axial loading co-exist. These complex stresses reduce to simple stresses. After that complete the design. Fig. Axial & Bending loading Combined (P+M) Fig. Eccentric…
SHEAR STRESSES IN BEAMS MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ on shear stresses greatly improves clarity of the topic. Further, it will be helpful in the design of beams. Shear stress is maximum at the centroidal axis and zero at the extreme fibers. Fig. Shear stress distribution in typical sections Fig. Variation of…
STRENGTH OF MATERIALS INTRODUCTION CLASS NOTES FOR MECHANICAL ENGINEERING Strength of materials tells which materials are strong in tension/compression/ bending /torsion/buckling. Hence depending upon the application, one can select the material for that application. Application includes chair, table, rod, shaft or any item one can think of. The selection is possible after performing tests under…
CASTIGLIANO’S THEOREMS CLASS NOTES FOR MECHANICAL ENGINEERING Castiglioni’s Method This method deals with displacements with respect to strain energy. Strain energy is also called potential energy. It is also named as Internal energy. Deflection is found using strain energy. Strain energy is recoverable as mechanical energy. Displacement in Castilian’s method means Extension under an axial tensile…
FATIGUE CLASS NOTES FOR MECHANICAL ENGINEERING It is the failure of material under reversal of stress. Fatigue reduces the strength of a material. Notable Fatigue Failures Versailles train disaster The 1862 Hartley Colliery Disaster De Havilland Comet crash Alexander L. Kierland oil platform capsizing The 1919 Great Molasses Flood The 1948 Northwest Airlines Flight…

Slope Deflection https://www.mesubjects.net/wp-admin/post.php?post=7644&action=edit Laminated springs FATIGUE MECHANICAL LIFE DESIGN-A REVIEW CLASS NOTES Abstract Fatigue is due to cyclic loading and unloading of one kind or the other. It is due to the presence of discontinuities in the material. Mostly fatigue failure is progressive and plastic in nature. It is…
SLOPE AND DEFLECTION CLASS NOTES FOR MECHANICAL ENGINEERING SLOPE It is angular shift at any point of the beam between no load condition and loaded beam. Its value is different at different points on the length of the beam. It is represented by dy/dx or θ. Its units are radians. There is a…
