The approximate carbon content in mild steel is?

Staggering of holes __________ the load carrying capacity of a tension member.

Which of the following elements is added to steel to increase its resistance to corrosion?

What is the recommended maximum percentage of Sulphur and Phosphorous content in steel?

What is the allowable direct tensile stress in structural steel? (where f_y is the yield stress or proof stress.)

A steel plate 150 mm wide and 12 mm thick is connected to a plate using 3 bolts of 16 mm dia on a single line. The net area of the plate is

The permissible stress in axial tension (σ_t) in a steel member on the net effective area of the section shall not exceed the following value (where fy is the yield stress)

A symmetric I-section (with width of each flange = 50 mm, thickness of each flange = 10 mm, depth of web = 100 mm, and thickness of web = 10 mm) of steel is subjected to a shear force of 100 kN. Find the magnitude of the shear stress (up to 2 decimal places, in N/mm²) in the web at its junction with the top flange______.

The critical bending compressive stress in the extreme fibre of a structural steel section is 1000 MPa. It is given that the yield strength of the steel is 250 MPa, width of the flange is 250 mm and thickness of flange is 15 mm. As per the provisions of IS : 800 2007, the non-dimensionless slenderness ratio of the steel cross section is (up to 1 decimal place)

Consider the following statements about the purpose of lug angles:

1. Lug angles are used to increase the lengths of the end connections of angle sections.

2. Lug angles are used to decrease the lengths of the end connections of angle sections.

3. Lug angles are used to increase the lengths of the end connections of channel sections.

4. Lug angles are used to decrease the lengths of the end connections of channel sections.

Which of these statements are correct?
