For the beam with a rectangular section and maximum stress of 120 N/mm2, and moment of inertia of 7 X 10^8 mm4, find the length of the beam carrying a uniformly distributed load of 40 kN/m.
- Length = 8.33 m
- Length = 10 m
- Length = 6.67 m (correct)
- Length = 12 m
For the timber beam with a rectangular section, if b= â…” d, find the value of b and d.
For the timber beam with a rectangular section, if b= â…” d, find the value of b and d.
- $b = 0.4 m$, $d = 0.6 m$ (correct)
- $b = 1.5 m$, $d = 2.25 m$
- $b = 2 m$, $d = 3 m$
- $b = 0.6 m$, $d = 0.9 m$
