Consider the structure and applied actions shown in the adjoining figure. The frame is subjected to a uniformly distributed load on AB, an initial curvature in CD and support settlement at A.
Use the dimensions and load values in the table shown in the attachment.
Analyse the structure for all actions applied simultaneously and determine the reactions, member forces and displacement required in the table below.

Steel balls 12 mm in diameter are annealed by heating to 1150 k and then slowly cooled to 400 k in an air att 325 k and h -20 w/m2 k. assume the properties of the steel to be k- 40 w/m k,p 7800 kg/m3, and cp 600 j/kg k. a. determine whether lumped system method can be used to analyze this problem and if so why" b. determine the time required for the cooling process. c. determine the total amount of heat lost from each ball to the ambient air
