mm
mild steel flat as shown in Fig. 1.46. If the combination is heared through 20°C determ
(i) The stress produced in each of the bar,
(ii) Shear force which tends to rupture the brazing, and
(iii) Shear stress
Take: a = 18.5 x 10 per°C;
a = 12 x 10 per°C;
E = 110 GN/m2
E = 220 GN/m
Length of each flat = 400 mm.
