The uniform beam of weight W is to be supported by the two rods, the lower ends of which were initially at the same level. Determine the ratio of the areas of the rods so that the beam will be horizontal after it is attached to the rods. Neglect the deformation of the beam.

This question relates to structural analysis. Please give detailed answer.

Classify each of the structures as statically determinate, statically indeterminate, stable, or unstable. If indeterminate, specify the degree of indeterminacy.

(ii) The bar has a cross-sectional area A, Length L, modulus of elasticity E and coefficient of thermal expansion a. The temperature of the bar changes uniformly along its length from T₁ at A to T at B so that at any point x along the bar T = T₁ + x(T-TA)/L. Determine the force the bar exerts on the rigid walls. Initially the bar has a temperature of TA A A в
