Question
Prob. 1
Four 50 mm x 200 mm dressed planks are used to carry a
super imposed load of "W" kN/m. The allowable bending
stress of the plank is 8.30 MPa. How should the four planks
be framed to give the maximum stiffness as a beam?
Determine also the safe uniform "W" kN/m that this beam
could carry if the span is 6 m and is assumed to be simply
supported.
