Question
Calculate the minimum radius (in mm) of the solid aluminium tent pole required to carry the weight of the
tent without buckling.
Assume the tent pole is restrained sufficiently at the top and base, such that the pole effective length can
be assumed to be equal to its actual length (H).
Where W = 141.4 kg , H = 2.7 m, and take gravity to be 10m/s? ,
Young's modulus of aluminium, Eal = 69,000 MPa
For a solid circlular cross-sectional area, moment of inertia, I = TTr 4/4 where r is the radius of the solid
circle.
Give your answer in mm to 1 decimal place. Do NOT include the units in your answer.
Weight of tent = W kg
