In Fig. E3.3–3, rigid bar ABC is supported by axial member (1), which has a cross-sectional area of 400 mm², an elastic modulus of E = 70 GPa, and a coefficient of thermal expansion of a = 22.5 × 10-6 /°C. After load P is applied co the rigid bar and the temperature rises 40°C, a strain gage affixed to member (1) measures a strain increase of 1,650 µɛ. Determine: a) the normal stress in member (1). 52.5 MPa (b) the magnitude of applied load P. 12.25 kN D c) the deflection of the rigid bar at C. 2.5 m (1) A В 1.4 m 1.0 m
