Two vertical bars one of steel and other of bronze each 2 m long and of equal area of cross
section hang vertically with 700mm distance between their axes. A rigid member is
connected to the lower ends of the bars. Calculate at what distance from the steel bar should
a concentrated load of 70 kN be applied on the rigid member so that elongation of the bronze
bar will be 1.5 times that of steel bar. Take modulus of elasticity of steel and bronze as
200 GPa and 100 GPa respectively :

(A) 500mm (B) 400 mm
(C) 350mm 0) 300mm

is 2 mm/hr and base flow is 5 cumecs, the peak flow of the storm is :
(^) 24 m%/s (B) 36 m/s
(C) 41 m%/s (D) 49 m/s

Which one is the possible case of an S? profile?

approximately :

(ಯ) 0.75 (B) 1.05

(0 1.5 0) 1.75
