The aluminum block has a rectangular cross section and is subjected to an axial compressive force of 8 kip. If the 1.5-in. side changed its length to 1.500132 in., determine the Poisson's ratio. Assume modulus of elasticity (E) = 10 x 10^3 ksi indicate the free body diagram

The truss is constructed from three aluminum alloy members, each having a cross-sectional area of A = 800 mm² and an elastic modulus of E= 70 GPa. Assume a = 3.4 m, b = 10.9 m, and c = 4.5 m. If the horizontal displacement of roller B must not exceed 6.4 mm calculate the maximum vertical load Pmax that can be supported by the truss. C L₂ a Answer: Pmax= P b KN B

This cylinder support has a diameter of 64mm, modulus of Elasticity of E = 200GPa. It is fixed at point A and point C. The support at A is concrete, so we know it is rigid. The support at C is considered rigid only if the reaction Force at C does not exceed 150kN. The heights/lengths are H_AC = 5.6m and H_AB = 2.6m. HAC A с B HAB

The rigid bar is pinned at A and supported by two aluminum rods, each having a diameter of 1 in. and a modulus of elasticity Eal = 10(103) ksi. If the bar is initially vertical, determine the force in each rod when the 2-kip load is applied.

The 2-inch-thick polymer block is bonded to the rigid support and to the steel plate, which is subjected to a vertical load of P = 60 kip. 3.2 in. If the shear modulus for the polymer is G = 245 ksi, determine the vertical deflection of the plate. 4.8 in. 2 in.

The modulus of elasticity for the steel cable is 25 (10)^6 psi. Determine the average stress in the cable under the applied load. Assume a linear stress strain curve.

If it is 4 mm long and subjected to an axial tensile load of 6 kNkN, determine its elongation. Assume linear-elastic behavior.
