the free end of the bar. The cross section of the beam is shown below. de magnitude and location of the maximum tensile and compressive bend beam. As usual, neglect the weight of the beam. 4mm 120 N 1mm 1mm Smm

Compound axial member ABC has a uniform diameter of d = 1.25 in. • Segment (1) is an aluminum [E1 = 10000 ksi] alloy. The length of segment (1) is L1 = 100 in. %3D Segment (2) is a copper [E2 = 17000 ksi] alloy. The length of segment (2) is L2 = 140 in. %3D When axial force Pis applied, a strain gage attached to copper segment (2) measures a normal strain of ɛ2 = 1500 uin./in. in the longitudinal direction. What is the total elongation of member ABC? L1 P L2 A Aluminum В d Copper c'P Answer: AL = in. %3D

The section of a thick beam has the dimensions shown in the figure below. Calculate the section properties lz, ly and Izy (Izy = product of inertia) referred to horizontal and vertical axes through the centroid of the section. Refer to Section 6 in your notes for properties of planed sections. Also determine the direct stress at the point A due to a bending moment My = 55 Nm. (Hint: use Page 7-9 in your notes) Ay A 5 mm 20 mm G 5 mm 5 mm 10 mm

Axial loads are applied to the compound rod that is composed of an aluminum segment rigidly connected between steel and bronze segments. What is the stress in each material given that P = 15 kN? Specify whether tension or compression. Bronze Aluminum Steel A=400 mm? A=600 mm? A= 300 mm? 2P 3P 4P P -3 m + 5 m -4m
