What is the weight of a steel I-beam 40 feet long with a cross-sectional area of 42 in2? Steel density is 0.283 lb/in3 .   Be careful of the units. Round to the nearest whole pound.

There are two approximate methods for estimation of steel quantities. For schools 1 ton per 15.05 m3 of structure, what is the estimation for a lintel of span 1500mm?

A steel rod 75 inches long with a cross sectional area of 0.25 in2 is held vertically firm at one end while a load of 2500 lb is suspended from the other end. If the rod stretches 0.025 inch, find the modulus of elasticity of the steel.

Can I get a step by step walkthrough?
