ISRO Mechanical & Aerospace 2012 - Question 7

All ISRO Mechanical & Aerospace papers | ISRO Mechanical & Aerospace 2012

A plate is held by a chain AB through hinge joints. The plate is pulled with a force T. The tension in the chain is given by

Figure for question 7, ISRO Mechanical & Aerospace 2012

  • A. (\sqrt{3}/2)T
  • B. (\sqrt{2}/3)T
  • C. T/2
  • D. 3\sqrt{2}T

Answer: D. 3\sqrt{2}T

Explanation: Based on moment equilibrium and geometry (often 45 degree angle implied by L,L dimensions), T_chain = 3 * $\sqrt{2}$ * T.
