A vertical bar consists of two prismatic segments A₁ and A₂ with cross-sectional areas of 30cm² and 25cm², respectively. Two segments are made of different material and have different density and modulus elasticity. Segment A₁ is made of aluminum, where density of aluminum is daluminum = 0.0265 and the modulus elasticity is Ealuminum = 70 GPa; while, segment A₂ is N cm² made of steel, where density of steel is dsteel = 0.0772- and the modulus elasticity is = Esteel = 200 GPa. The vertical bar is subjected to three forces: Pg = 150 N ; Pc = 250 N ; Pp 100 N. The weight of the bar should be considered. Please answer in N and mm, and answers, in (b), (c), and (d) should be expressed in scientific notation (). (a) Calculate the reaction force at point A.
