answer number 2 only

Problems: 1. A square aluminum bar should not stretch more than 1.4 mm when it is subjected to a tensile load. Knowing that E = 70 GPa and that the allowable tensile strength is 120 MPa, determine the maximum allowable length of the bar. 2. An aluminum rod shown has a circular cross-section and is subjected to an axial load shown. Determine the total elongation of the rod when the load is applied. Take E=70 GPa. - 250 mm- 300 mm 30 kN 40 kN da =150 mm d 200 mm 3. The rigid bar ABC is supported by a pin at A and a steel rod at C. Determine the largest vertical load P that can be applied at B if the stress in the steel rod is limited to 30 ksi and the vertical movement of point B must not exceed 0.01 in. Neglect the weights of the members. Steel L- 4 ft A- 0.50 in E- 29 x 10* psi 4. The horizontal bar shown is supported by a pin at A and two rods with identical length. Determine the stress in each rod when the force W = 10 kips is applied. Steel A = 0.5 in E- 29 x 10° psi Bronze A - 2 in? E- 12 x 10° psi -3 ft 6 ft 3 ft
