Rigid bar ABC is supported by two identical solid bronze [σy=331 MPa; E = 105GPa; α= 22.0 x 10-6/ °C] rods and a single solid steel [σy=250 MPa; E=200GPa; α=11.7x10-6/°C] rod. Bronze rods (1) each have diameter d1=25 mm and L1=3.0 m. Steel rod (2) had lenght L2=4.0 m. a) Calculate the Diameter d2 required for steel rod (2) so that the deflection of joint B is zero for any change in temperature. b) Using the value of d2 determined in part (a), determine temperatur decrease that is allowable for this assembly if a factor of sfety of 2.0 is specified for the normal stress in each

Rigid bar ABC is supported by two identical solid bronze [σy=331 MPa; E = 105GPa; α= 22.0 x 10-6/ °C] rods and a single solid steel [σy=250 MPa; E=200GPa; α=11.7x10-6/°C] rod. Bronze rods (1) each have diameter d1=25 mm and L1=3.0 m. Steel rod (2) had lenght L2=4.0 m.
a) Calculate the Diameter d2 required for steel rod (2) so that the deflection of joint B is zero for any change in temperature.
b) Using the value of d2 determined in part (a), determine temperatur decrease that is allowable for this assembly if a factor of sfety of 2.0 is specified for the normal stress in each rod.
