Question 8Safety & Environmental - QMED

The correct answer is B) Strong back. A strong back is a long bar or beam used in shoring to distribute the pressure of a shore. It helps to spread the load across a wider area, providing additional support and stability. This is a key feature of strong backs that makes them well-suited for shoring applications. The other answer choices are not correct. A wedge is a tapered piece of wood used to tighten or secure a shore, while a shole is a horizontal timber or plank placed under a shore. A beam, while also a type of shoring material, does not specifically serve the purpose of distributing the pressure like a strong back.
