Concrete block weighing 20,000 lb is supported by 2 STEEL rods

In summary, the conversation discusses a concrete block weighing 20,000 lb supported by two STEEL rods with different areas. The question is about finding the elongation of each rod, and the suggestion is to start by finding the reactions of the rods on the block. The conversation ends with the person finding the answer.

a concrete block weighing 20,000 lb is supported by 2 STEEL rods, rod AB has an area of 1 in and rod CD has an area of 2 in...

what is the elongation of each rod...?

i don't know how to start, should i take reactions of the concrete block??

any help will be appreciated.
Finding reactions of the steel rods on the concrete block would be a good start. Can you find them? Then what?

wooo thanks i found the answer !
 

What is the purpose of supporting a concrete block with steel rods?

The purpose of supporting a concrete block with steel rods is to provide additional strength and stability to the structure. The steel rods help distribute the weight of the block evenly and prevent it from collapsing or cracking.

How does the weight of the concrete block affect the steel rods?

The weight of the concrete block has a direct impact on the steel rods supporting it. As the block is very heavy at 20,000 lb, the rods must be strong enough to withstand this weight without bending or breaking.

What type of steel is typically used for supporting heavy concrete blocks?

Steel rods used for supporting heavy concrete blocks are typically made of high-strength steel, such as carbon steel or alloy steel. These types of steel have a higher tensile strength and can withstand heavier loads.

How many steel rods are needed to support a concrete block weighing 20,000 lb?

The number of steel rods needed to support a concrete block weighing 20,000 lb depends on the size and dimensions of the block, as well as the strength of the steel rods. Generally, at least 2 steel rods are needed for proper support, but more may be required for larger or heavier blocks.

What factors should be considered when choosing steel rods for supporting a concrete block?

When choosing steel rods for supporting a concrete block, factors such as the weight and size of the block, the type of steel used, and the load-bearing capacity of the rods should be considered. It is important to select steel rods that are strong enough to support the weight of the block without bending or breaking.
