COMBINED BENDING, DIRECT AND TORSIONAL STRESSES IN SHAFTS Cases arise such as in propeller shafts of ships where a shaft is subjected to direct thrust in addition to bending moment and torsion. In such cases the direct stresses due to ...

TORSION OF SHAFTS
When a cylindrical shaft is subjected to equal and opposite couples at the ends, either it will be in equilibrium or it will rotate at a uniform rate. In either case, it is subjected to torsion and the stresses set ...
Theory of Simple Bending
When a beam is subjected to a loading system or by a force couple acting on a plane passing through the axis, then the beam deforms. In simple terms, this axial deformation is called as bending of a beam. Due to ...
FLITCHED BEAMS
Beams that are built of more than one material are called composite beams. Examples are bimetallic beams, which consists of two different metals bonded together, sandwich beams, and reinforced concrete beams. Composite beams may be analysed by the same bending ...
Determinate and Indeterminate Structures and Their DIfferences
Structure is generally classified into two categories as Determinate and Indeterminate Structures or Redundant Structures for analysis of structures to find forces based on criteria discussed below. Structure is an assemblage of a number of components like slabs, beams, columns, ...
MOMENT AREA METHOD
MOMENT AREA METHOD OF STRUCTURAL ANALYSIS: Theorem – I The change in slope between tangents drawn to the elastic curve at any two points A and B is equal to the product of and the area of the moment diagrams ...
Prestressed Concrete- Advantages and Disadvantages
Prestressed concrete is the most durable, reliable and strongest concrete that is widely used for the construction of mega buildings and bridges. It is a type of concrete in which high-strength tendons placed in tension regions of the cross-section are ...
Pre-Tensioning and Post-Tensioning in Prestressed Concrete Design
The prestressed concrete design of a structure is influenced by either of the two processes, pre-tensioning, and post-tensioning. Pre-tensioning can be further classified into two categories such as linear pre-tensioning and circular pre-tensioning. Pre-Tensioning and Post-Tensioning in Prestressed Concrete Design ...
