A bar of steel and a bar of aluminum e the dimensions shown in the figure. Calcu- MS 52 A wall bracket is constructed as shown in the figure. All joints may be considered pin- 2-11. connected. The steel rod AB has a cross-sectional area of 5 mm². The member BC is a rigid beam. If a 1.00 m diameter frictionless drum weighing 4 500 N is placed in the position shown, what will the elongation of the rod AB be? Ans: 8.04 mm. 1.80 m -4 500 N drum 2.40 m Pinned joint PROB. 2 - 11 1.50 m

Two disks are connected by four rods, as shown in Figure P3–70. All rods are 6.0 mm in diameter and have the same length. Two rods are steel (E = 207 GPa), and two are aluminum (E = 69 GPa). Compute the stress in each rod when an axial tensile force of 11.3 kN is applied to the disks.

A torsional bar is subjected to two external torques (10Nm and 5Nm) and a distributed torque(15Nm/m) at the locations indicated in the picture. The angle of twist at A (z = 0) is 0. Theshear modulus is 2GPa., if the bar has both A and C fixed (i.e., the torque applied at C is replaced by a fixed support), find the angle of twist at B.

Repeat Problem 2.3-4, but now include the weight of the bar. Sec Table 1.1 in Appendix I for the weight density of steel.

Repeat Problem 11.3-9. Use two C 150 × 12.2 steel shapes and assume that E = 205 GPa and L = 6 m.
