This document gives the class notes of Unit 6: Bending and shear Stresses in beams. Subject: Mechanics of materials.
Syllabus contest is as per VTU, Belagavi, India.
Notes Compiled By: Hareesha N Gowda, Assistant Professor, DSCE, Bengaluru-78.Chapter 6: Pure Bending and Bending with Axial Forces

This summary provides the key points about pure bending and bending with axial forces from the document:
1. Pure bending occurs when a beam segment is in equilibrium under bending moments alone, with examples being a cantilever loaded at the end or a beam segment between concentrated forces.
2. For beams with symmetric cross-sections, plane sections remain plane after bending according to the fundamental flexure theory. The elastic flexure formula gives the normal stress as proportional to the bending moment and the distance from the neutral axis.
3. The second moment of area, or moment of inertia, represents the beam's resistance to bending and is used to calculate maximum bending stresses. The elastic section modulus is a ratio of the moment

Axial force, shear force, torque and bending moment diagram

This document introduces shear force, bending moment, and torque diagrams. It discusses:
1. The purpose of these diagrams is to visualize the internal forces along a member under loading conditions.
2. Two methods are presented for constructing these diagrams - the basic method uses equilibrium equations, while the graphical method uses relationships between loading, shear, and bending.
3. Examples are provided to demonstrate the application of both methods to calculate shear force and bending moment diagrams for beams under different load scenarios.

Portal and cantilever method

Approximate analysis methods make simplifying assumptions to determine preliminary member forces and dimensions for indeterminate structures. Case 1 assumes diagonals cannot carry compression and shares shear between diagonals. Case 2 allows compression in diagonals. Portal and cantilever methods analyze frames by dividing into substructures at assumed hinge locations, solving each sequentially from top to bottom.

Chapter 2: Axial Strains and Deformation in Bars

This document discusses stress-strain relationships in materials subjected to axial loads. It covers key concepts such as elastic and plastic deformation, ductile and brittle behavior, stress-strain diagrams, and the effects of temperature, strain rate, and time-dependent behavior like creep and stress relaxation. Measurement techniques for strain like strain gages and extensometers are also described. Various stress-strain models are presented, including Hooke's law, the Ramberg-Osgood equation, and idealized perfectly plastic, elastic-plastic, and strain hardening models. The relationships between stress, strain, elastic modulus, yield strength, and other mechanical properties are examined through diagrams and equations.

Bending Stress In Beams

This document discusses bending stresses in beams. It defines simple or pure bending as when a beam is subjected to a bending moment that causes stresses but no shear stresses. The assumptions of pure bending theory are that the beam material is isotropic, homogeneous, initially straight, and elastic limits are not exceeded. Pure bending causes some layers to compress and others to tensile. A neutral axis experiences no stress. Bending stresses are calculated using the bending equation relating bending moment, moment of inertia, and distance from the neutral axis. Flitched or composite beams made of different materials also follow bending equations.

Lecture 11 shear stresses in beams

This document discusses stresses in beams, specifically shear stresses. It covers five lectures on related topics like bending moment and shear force diagrams, bending stresses, shear stresses, deflection, and torsion. For shear stresses in beams with rectangular cross-sections, it explains that both normal and shear stresses are developed when loads produce both bending moments and shear forces. The maximum shear stress occurs at the center of the beam and its distribution is parabolic. Equations are provided for calculating shear stress values.

Unsymmetrical bending and shear centre

This document discusses unsymmetrical bending of beams. Unsymmetrical bending occurs when the beam cross-section is not symmetrical about the plane of bending, or when the load line does not pass through a principal axis of the cross-section. The document defines principal axes as those passing through the centroid where the product of inertia is zero. It presents equations to calculate the principal moments of inertia and product of inertia for a given cross-section, and describes how to determine the principal axes by setting the product of inertia equal to zero.

Ace 402 lec 3 bending

This document discusses material properties and bending stresses. It defines key terms like modulus of elasticity, Poisson's ratio, yield stress, and ultimate tensile stress. It explains that plane sections remain plane after bending but rotate, and that the neutral axis experiences no deformation or stress. The location of the neutral axis depends on the material properties and loading conditions. Equations are provided to calculate bending stresses based on the neutral axis location and applied moment. An example problem calculates bending stresses at different points on an airplanes wing. The document also notes that for very high loads above the elastic range, stresses become nonlinear and the neutral axis must be determined through trial and error.

Centroid and Moment of Inertia from mechanics of material by hibbler related ...

Centroids and moment of inertia are important concepts in mechanics. The centroid of a plane figure is the point where the entire area is considered to be concentrated. It is found by suspending the figure from different corners and finding the intersection point of vertical lines. The center of gravity is where the entire mass is considered concentrated. For uniform plane figures with no weight, the centroid and center of gravity coincide. The moment of inertia is a measure of an object's resistance to changes in rotation or bending and depends on the object's mass distribution and axis of rotation. It is calculated based on the object's area or mass distances from the axis of rotation.

Modeling and Structural Analysis of a Wing [FSI ANSYS&MATLAB]

In our study, analyzing aircraft’s wing with the old assumptions will not give an exact solution but
this solution (total deformation) changes according to the geometry of the cross-section of the beam, so
the total deformation of the beam may be greater or lower than the exact solution. In these two cases,
the solution is not acceptable as in the first case which the deformation is greater than the exact solution
will make more weight and cost, and Engineers design aircraft at minimum weight and less cost. But in
the second case which will make lower deformation than exact solution will be much risky as the aircraft
could fail at any time, and this case much dangerous because it threatens the life of people.

Truss analysis by graphical method

The document discusses three methods for analyzing trusses: the method of joints, method of sections, and graphical (Maxwell's diagram) method. The method of joints involves isolating each joint as a free body diagram and using equilibrium equations to solve for unknown member forces. The method of sections uses equilibrium equations applied to portions of the truss cut off by an imaginary section through several members. Maxwell's diagram method constructs force polygons representing the forces at each joint to graphically determine member forces.
