The thin rectangular plate is uniformly deformed such that Ex = 220E, Ey= -680 uE, and yy = 870 urad. If a = 35 mm, determine (a) the normal strain &, in the plate. (b) the normal strain &, in the plate. (c) the shear strain ynt in the plate. B D. a a a a a a a a a Answers: (a) En= i HE (b) Et= i HE (c) Ynt = i prad

If the maximum bending stress at section a–a is not allowed to exceed an allowable stress of 220 MPa, determine the maximum allowable force P that can be applied to the end E.

The copper rod AB and steel rod BC are joined at the collar B and fixed connected at their ends. If there is no load in the members when T1 = 17°C, determine the average normal stress in each member when T2 = 47°C. Also, how far will the collar be displaced? The cross-sectional area of each member is 1130 mm?. %3D Сopper Steel Elastic Modulus (GPa) 120 200 Coefficient of thermal expansion (1/°C) 17x10-6 12x10-6 В 1 m 0.6 m-
