Question
A steel rod of cross-sectional area 16 cm2 and two brass rods of cross section area 10 cm2 together support a load of 5000 kg as shown in figure. The stress in steel rod will be :
(Take Y for steel = 2.0 × 106 N/cm2 and for brass = 1.0 × 106 N/cm2)
(Take Y for steel = 2.0 × 106 N/cm2 and for brass = 1.0 × 106 N/cm2)
Options
A.161.2 N/cm2
B.151.4 N/cm2
C.131.4 N/cm2
D.None of these
Solution
in balanced condition F1 + 2F2 = 5000 g
F1 = 5000 g ⇒ F1 = 2580 gSo stress in steel rod
= 161.2 kg /cm2Create a free account to view solution
