Q1. Formula for Unit weight of steel rebar
Ans. 
Unit weight of steel rebar is calculated using a specific formula based on the dimensions of the rebar.
• Unit weight of steel rebar = (D^2/162.2) * L, where D is the diameter of the rebar in inches and L is the length of the rebar in feet.

• The formula is derived from the weight of a steel bar per foot, which is 3.4 pounds for a rebar with a diameter of one inch.

• For example, a steel rebar with a diameter of 0.5 inches and ...read more
