A structural steel bar with a 3.6 in. × 0.890 in. rectangular cross section is subjected to a tensile axial load of 54 kips. Determine the maximum normal and shear stresses in the bar. Answer: Omax = i ! ksi Tmax i ! ksi

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

The total cross-sectional area of the load-bearing calcified portion of the two forearm bones (radius and ulna) is approximately 2.3 cm2. During a car crash, the forearm is slammed against the dashboard. The arm comes to rest from an initial speed of 80 km/h in 5.1 ms. If the arm has an effective mass of 3.0 kg, what is the compressional stress that the arm withstands during the crash? Pa

Calculate the value of the stress if the volume of the cube is reduced by 0.15%. 250MPa 350 MPa 200 MPa 300 MPa 7 A 5-m rod having a uniform cross sectional area of 1000 square mm is secured between two walls 5 meters apart. The load on the rod is zero at 27 deg.Celsius E = 200 GPa and the linear 28°C At H
