supportedbeam. A beam that has pin support at either ends, or a pin at one end and a roller support at the other is called a simplysupportedbeam. The pin support is capable of developing a force reaction in its horizontal and vertical components, but it cannot develop a moment reaction. The roller...
shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion.
The diagram shows a beam carrying loads . It is simplysupported at two points where the reactions are . Assume that...
which is represented by dotted line in Fig.3.8(a). A reasonable procedure is to assume fixed end moment in the range of wl2/10, where l is clear span and w is magnitude of uniformly distributed load.

1. PROCEDURE
• Assemble the apparatus as a simplysupportedbeam with a span of 900mm. Adjust the equipment so that the beam is horizontal, the spring balances, and beam supports are vertical. Note the spring...

the midspan. The maximum of maximum bending moments is
called the absolute maximum bending moment.
4. Where do you have the absolute maximum bending moment in a simplysupportedbeam when a series of
wheel loads cross it?
When a series of wheel loads crosses a simplysupportedbeam, the...

. Cantilever beam: A beam which is fixed at one end and at the other end is known as cantilever beam.
2. Simplysupportedbeam: A beamsupported or resting freely on the supports at its both end is known as simplysupportedbeam 3. Fixed beam: A beam whose both end are fixed or built-in walls is...
which is fixed at one end in this way is called a Cantilever. If both
ends are fixed in this way the reactions are not statically determinate.
2. SimplySupported:
A beam that has hinged connection at one end and roller or pin connection in other end
is called simplysupportedbeam

It is normal practice to produce a free body diagram with the shear diagram and the bending moment diagram position below For simplysupportedbeams the reactions are generally simple forces. When the beam is...

of such a beam will then be equivalent to an initially horizontal cantilever, with a span that is half of that of the simplysupportedbeam. This situation is illustrated in Fig. 4.
Now, if the resultant reactions at the supports of the simplysupportedbeam are assumed to be normal to the...
