Comprehension # 9 A 10ml mixture of N_(2) , a alkane & O_(2) undergo combustion in Eudiometry tube. There was contraction of 2ml , when residual gases are passed are passed through KOH . To the remaining mixture comprising of only one gas excess H_(2) was added & after combustion the gas product is absorbed by water. causing a reduction in volume of 8ml . Gas produced after introduction of H_(2) in the mixture?

In nature the failure of structural members usually result from large torque because of twisting or bending rather than due to tensile or compressive strains. This process of structural breakdown is called buckling and in cases of tall cylindrical structures like trees, the torque is caused by its own weight bending the structure. Thus, the vertical through the centre of gravity does not fall within the base. The elastic torque caused because of this bending about the central axis of the tree is given by (Ypi r ^(2))/(4R) Y is the Young's modulus, r is the radius 4R of the trunk and R is the radius of curvature of the bent surface along the height of the tree containing the centre of gravity (the neutral surface). Estimate the critical height of a tree for a given radius of the trunk.
