[amp_mcq option1=”Structural works in beams” option2=”Small sized water pipes” option3=”Columns and struts” option4=”None to these” correct=”option3″]<\/p>\n
The correct answer is: C. Columns and struts<\/strong><\/p>\n Cast iron is a type of iron that is made by melting iron and then pouring it into a mold. It is a strong and durable material that is often used in construction. Cast iron is used for columns and struts because it is strong and can support a lot of weight. It is also resistant to corrosion, which makes it a good choice for use in outdoor applications.<\/p>\n Option A is incorrect because cast iron is not typically used for structural works in beams. Beams are structural elements that support the weight of a building or other structure. They are typically made from steel or concrete, which are stronger materials than cast iron.<\/p>\n Option B is incorrect because cast iron is not typically used for small sized water pipes. Water pipes are typically made from PVC, copper, or steel, which are all more corrosion-resistant materials than cast iron.<\/p>\n Option D is incorrect because cast iron is used for columns and struts.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Structural works in beams” option2=”Small sized water pipes” option3=”Columns and struts” option4=”None to these” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[644],"tags":[],"class_list":["post-6343","post","type-post","status-publish","format-standard","hentry","category-building-materials","no-featured-image-padding"],"yoast_head":"\n
