What can be derived from the shear force?
Shear force in a cantilever beam at the support due to a concentrated load is equal to the magnitude of the concentrated load (or sum of the loads) regardless of their position along the beam. Shear force in a cantilever beam increases linearly from zero at the free end to a magnitude of (wL) at the support, where w is the uniform load and L is the length of the beam.
What is the significance of shear center?
It is very important to find the shear center for the beams or sections that are undergoing majority of the load under torsion or twisting then the material will not fail under torsion as at shear centre there will be no effect of torsion or twisting. It will fail only by bending or any other force.
What are the purposes of providing shear reinforcement in beam . Explain with suitable sketch?
beams is tying
A bent rod to resist shear and diagonal stresses in a concrete beam is called?
STIRRUPS
What kind of stresses are produced in a beam during transverse vibration?
If you load it normal to the beam axis you get bending stresses ( tension and compression) and shear stresses. If you load it along the axis you get axial stress ( tension or compression)
What is negative shear and Positive shear in beams?
The difference between a positive shear and a negative shear is the direction the beam is distorted into. A force that tends to shear the left portion of the beam upward with respect to the right portion is said to produce a positive shearing force.
What does steel stirrup do in reinforced concrete beam and column?
It proves shear reinforcement in the beam.
What does stirrup do to reinforced concrete beam?
to resist shear force
What are the different between simply supported restrained beam and simply supported unrestrained beam?
because the deflection in simple suported beam is more due to the orestriction at the ends as the ends are freely supported by twoo supports

The difference between shear force diagram and shear force influence line diagram?
A shear force diagram is used to give the value of shear force at any point on the beam due to static load while the influence line gives the effect of a moving load at any point on the beam. Abdul Nafay Achakzai

What is the advantage and disadvantages of fixed beams?
There isn't really an advantage of having a fixed beam vs. a simply supported beam, it depends on what application the beam is for. If one of the design criteria of the beam is that it be able to deflect from one end to another then you are going to want to use a fixed beam. For example such applications could include a diving bored. A simply supported beam differs from a fixed beam because the beam is supported at both ends. Thus when a simply supported beam is loaded, the deflection will occur throughout the beam, since the ends are confined and will remain as they were. Furthermore on a fixed beam, (the end that is fixed) will have restrictive forces and moments keeping the end from moving.
What is difference center of shear and center of twist?
The shear center is the point on a beam cross section at which an applied shear force (lateral load or load parallel to the cross section) will produce bending but no twisting of the section. The center of twist is a point in a cross section that remains stationary when a twisting moment (torque) is applied on that cross section. The shear center and twist center are the same point only when the beam is rigidly supported.
What is a fixing moments of a fixed beam?
A fixed beam is a beam the ends of which are constrained or built-in to remain in horizontal position. Point to be noted for the fixed beam: 1. The beam is stiffer, stronger and more stable. 2. The slope at both the ends is zero. 3. Due to the fixidity, the moment will be induced at each end. 4. The induced moments will be in the opposite direction to that of moments due to external loading.
