Q1: An engineer's hammer is made of high __________ steel.

ANS:A - carbon

An engineer's hammer is typically made of high carbon steel. Explanation:

1. High Carbon Steel: High carbon steel contains a higher percentage of carbon compared to other types of steel. It typically contains between 0.60% and 1.5% carbon by weight. The high carbon content gives the steel increased hardness, strength, and wear resistance.
2. Properties: High carbon steel is known for its ability to hold a sharp edge and withstand impact and deformation without becoming deformed itself. These properties make it suitable for applications where toughness and durability are required, such as in tools and machinery components subjected to high stress and impact loads.
3. Engineer's Hammer: An engineer's hammer, also known as a hand sledge or drilling hammer, is a type of hammer used for striking chisels, punches, and other tools in metalworking, woodworking, and construction applications. It is typically heavier than a regular hammer and has a larger striking face to deliver more force with each blow.
4. Material Selection: Engineer's hammers are commonly made of high carbon steel due to its hardness and durability. This ensures that the hammer can withstand repeated use without deforming or breaking. The high carbon content allows the hammer to deliver powerful blows without becoming damaged, making it suitable for heavy-duty tasks.
