This means that it is very strong under compression, but not so strong under tension. This is because cast iron is a brittle material, which means that it can easily crack or break when it is under tension.<\/p>\n<p>Mild steel, on the other hand, is a ductile material, which means that it can be stretched and deformed without breaking. This makes mild steel more resistant to tensile forces than cast iron.<\/p>\n<p>In general, cast iron is used in applications where it will be under compression, such as in the construction of buildings and bridges. Mild steel is used in applications where it will be under tension, such as in the construction of cars and airplanes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;(i) and (ii)&#8221; option2=&#8221;(ii) and (iii)&#8221; option3=&#8221;(iii) and (iv)&#8221; option4=&#8221;(i) and (iv)&#8221; correct=&#8221;option2&#8243;]<\/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-6365","post","type-post","status-publish","format-standard","hentry","category-building-materials","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Compared to mild steel, cast iron has (i) High compressive strength (ii) High tensile strength (iii) Low compressive strength (iv) Low tensile strength A.
