What modulus of elasticity in tension is required to obtain a unit deformation of 0.00105 m/m from a load producing tensile stress of 44,000 psi? A) 41.9x106 B 41.2x106 42.3x106 D 43.1x106

1 iron 40 cm steel 70 cm Henry has a rod that is made out of 2 parts. An iron and steel section. The iron section is 40cm long (Y₁=9.1 x 10¹⁰ N/m²). The iron piece is attached to a steel piece that is 70 cm long (Y,=7.0 x 10¹0⁰ N/m²). The rod has a uniform cross sectional diameter of 3.40 cm. Determine the total compression (in mm)when henry uses a compressive force on the rod of magnitude F=6000N. Look at the image provided to get a better understanding.

Between AB there is a 20 cm aluminum wire that supports a mass of 490 g and between BC another bronze cable of length 10 cm that supports a mass of 245 g; where EAL = 0.2x10¹¹ Pa (Young's modulus) and EBr = 5x10¹¹ Pa; with equal cross sections S = 0.2 cm² determine what length reaches point C. A - B - C

Two wooden members, each having a width of b = 2.4 in. and a depth of d = 0.8 in., are joined by a simple glued scarf joint. Assume B = 47°. If the allowable shear stress for the glue used in the joint is 94 psi, what is the largest axial load P that may be applied? Answer: P = i ! Ib
