In a continuous curve of bending moment, the point of zero bending moment, where it changes sign is called
The beam is loaded as shown in figure. Select the correct BM diagram
BMD will be of 2nd degree, so the correct answer is (d).
The structure shown in the figure below will be stable if
∴ 2x2 = y2
A beam 8 m long, simply supported at the ends, carries a point load of 1000 N at the mid-span. The bending moment under the load is
A simply supported beam is loaded as shown in the above figure below.
The maximum shear force in the beam will be
Taking moment about A = 0
R2 = 2W
But, ∑Fv = 0
⇒ W + 2W + W - R1 - R2 = 0
⇒ R1 = 4W - 2W = 2W
Which one of the following portions of the loaded beam shown in the given figure is subjected to pure bending?
Since the given beam is loaded symmetrically, therefore the reactions at each suportwill be equal i.e. W
In section BD, shear force is zero. Hence this section subjected to pure bending.
The point of contraflexure in a beam is at the location where the
The rate of change of bending moment is equal to
M = V · x
dM/dx = V
i.e. Rate of change of bending moment is shear force.
The BM diagram of the beam shown in figure is
Taking moments about A. We get
M - R2 + L = 0
⇒ R2 = M/L
Since these is no vertical loading hence the reactions are equal and oposite.
Bending moment is given by
A cantilever carrying uniformly distributed load W over its full length is propped at its free end such that it is at the level of the fixed end. The bending moment will be zero at its free end and also at
