Mechanical 4 Beams

How could the UDL (uniform distributed load) above be represented?

• by a force of 18kN downwards at point B

• by a force of 18kN downwards midway between point A and B

• by a force of 3kN downwards midway between point A and B

• by a force of 3kN downwards in the wall

What can you say about the bending moment at each end of a simply supported beam?

• both ends always have zero bending moment

• the end nearest the largest force will have the greatest value

• the end you start with will be zero and the other end will have to be calculated

• it is equal to the reaction force at both ends

What can you say about the bending moment of a cantilever beam?

• neither end of the beam will have a bending moment of zero

• both ends of the beam will have a bending moment of zero

• the end attached to the wall will always have a bending moment of zero

• the end not attached to the wall will always have a bending moment of zero
