Figure Q12 shows a prospective design for a conveyor roller system, for transferring
crates, one at a time. The system is made up of two parallel rectangular steel
beams, built-in at one end and simply supported at the other, with closely spaced
rollers mounted in-between, for the crate to pass over.
a) Using Macaulay notation, carry out an analysis of the problem and calculate
the deflection of the mid-length point of the beams when the crate is
centrally located, midway between A and B. State any important
assumptions used in your analysis.
[20 marks]
b) Comment briefly whether this would be the maximum deflection of the beams
when the crate is centrally located.
