Types of Loads
1- Concentrated load assumed to act at a point and immediately introduce an oversimplification since all practical loading system must be applied over a finite area.

2- Distributed load are assumed to act over part, or all, of the beam and in most cases are assumed to be equally or uniformly distributed.

a- Uniformly distributed load.

a- Uniformly varying load.

Concept of Shear Force and Bending moment in beams:
When the beam is loaded in some arbitrarily manner, the internal forces and moments are developed and the terms shear force and bending moments come into pictures which are helpful to analyze the beams further. Let us define these terms

Now let us consider the beam as shown in fig 1(a) which is supporting the loads P1, P2, P3 and is simply supported at two points creating the reactions R1 and R2 respectively. Now let us assume that the beam is to divided into or imagined to be cut into two portions at a section AA. Now let us assume that the resultant of loads and reactions to the left of AA is ?F' vertically upwards, and since the entire beam is to remain in equilibrium, thus the resultant of forces to the right of AA must also be F, acting downwards. This forces ?F' is as a shear force. The shearing force at any x-section of a beam represents the tendency for the portion of the beam to one side of the section to slide or shear laterally relative to the other portion. Therefore, now we are in a position to define the shear force ?F' to as follows: At any x-section of a beam, the shear force ?F' is the algebraic sum of all the lateral components of the forces acting on either side of the x-section.

Sign Convention for Shear Force:
The usual sign conventions to be followed for the shear forces have been illustrated in figures 2 and 3.

Concept
A transverse load is applied to a beam. The beam changes its shape and experiences bending moment. Internal stresses (bending stress) develop in the beam.
In the bent or curved shape, the material on the inside of the curve experiences compression and material on the outside of the...

...Abstract:
On this project we will try to design an ( I ) construction beam and find lightest weight material that can be used as an construction beam , currently we are taking strength of material course that helping us to learn more about construction beam’s design , we will be going over types of beams , types of loads and beams design , on our own we will research about the materials of beams and try to...

...implementing change. With changes, organizations need to take steps to fully plan the change in order to ensure a smooth transition and acceptance (Spector, 2013). Research will show how Duke University Children’s Hospital assessed the internal and external forces that impacted the change and how they assessed if the organization was ready for change. Also, research will show what model and strategies were used during the organizational change along with an...

...In every organization, there is an overload of forces that may occur internally as well as externally that will impact organizational behavior. In order to understand what how an organization is functioning we have to concentrate on a broader perspective and we have to analyze the people that are actually building blocks of the organizations. Hence the study of organizational behavior means studying the structure, the functioning, the performance and the behavior of people in an...

...Three: Parallam Beam Deflection
Lab Group - 1st Mondays, Late: Jesse Bertrand, Ryan Carmichael, Anne Krikorian, Noah Marks, Ann Murray Report by Ryan Carmichael and Anne Krikorian
E6 Laboratory Report – Submitted 12 May 2008 Department of Engineering, Swarthmore College
Abstract:
In this laboratory, we determined six different values for the Elastic Flexural Modulus of a 4-by10 (100” x 3.50” x 9.46”) Parallam wood-composite test beam. To accomplish this, we...

Abstract
An equation for the determination of large deflections of beams is derived from first principles. Laboratory tests were carried out in order to validate the theory. The theoretical and experimental results were found to be in good agreement.
Introduction
In much of the study and...
