A rigid bar PQR is hinged at its end P. As shown in the figure, the bar is pin- connected through two identical links QS and RT at points Q and R, respectively. The other ends of the links, S and T, are fixed. Both links are made of the same material. If the temperature of the links is uniformly increased by ΔT, then which one of the following statements is correct? (Neglect the weight of the rigid bar)
- A. Both QS and RT will be stress free.
- B. Both QS and RT will be under tension.
- C. Both QS and RT will be under compression.
- D. QS will be under compression and RT will be under tension.
Answer: D. QS will be under compression and RT will be under tension.
