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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
