A rigid beam of negligible weight is supported in a horizontal position by two rods of steel and aluminum, 2m and 1m long having values of cross-sectional areas 1 cm2 and 2 cm2 and E of 200 GPa and 100 GPa respectively. A load P is applied as shown in the figure.
If the rigid beam is to remain horizontal then
  • a)
    the forces on both sides should be equal
  • b)
    the force on aluminum rod should be twice the force on steel
  • c)
    the force on the steel rod should be twice the force on aluminum
  • d)
    the force p must be applied at the center of the beam
Correct answer is option 'B'. Can you explain this answer?

If the beam is to remain horizontal ⇒ δAB = δCD Let force on rod AB be P′
⇒ Force on rod CD = P − P′
⇒ 2P′ = P − P′
⇒ 3P′ = P
⇒ P′ = P/3(force on steel rod) Force on aluminum rod
⇒ Force on aluminum rod
= 2 x force on steel rod.
