Which of the following are statically determinate beams?

• Only simply supported beams

• Cantilever, overhanging and simply supported

• Fixed beams

• Continuous beams

A cantilever is a beam whose

• Both ends are supported either on rollers or hinges

• One end is fixed and other end is free

• Both ends are fixed

• Whose both or one of the end has overhang

For any part of a beam subjected to uniformly distributed load, Shear force diagram is

• Horizontal straight line

• Vertical straight line

• Line inclined to x-axis

• Parabola

Point of contra-flexure is a

• Point where Shear force is maximum

• Point where Bending moment is maximum

• Point where Bending moment is zero

• Point where Bending moment=0 but also changes sign from positive to negative

Point of contra-flexure is also called

• Point of maximum Shear force

• Point of inflexion

• Point of maximum Bending moment

• Fixed end

In a simply supported beam, bending moment at the end

• Is always zero if it does not carry couple at the end

• Is zero, if the beam has uniformly distributed load only

• Is zero if the beam has concentrated loads only

• May or may not be zero

The shear force is zero at a section where the bending moment will be

• zero

• maximum

• minimum

• maximum or minimum

For a simply supported beam with point load at centre, the bending moment will be maximum at

• left end

• right end

• both ends

• the middle of the beam

For a beam subjected to a constant bending moment throughout its length

• The shear force at all sections is zero

• The shear force at all sections is constant

• The shear force varies linearly along the length of the beam

• none of the above

A roller support in a beam

• Shear force is zero

• Bending moment is zero

• Bending moment is maximum

• Slope is zero
