Unit weight of circular bar can be calculated using a specific formula.

• The formula to find the unit weight of a circular bar is: Unit weight = (π * D^2 * L * ρ) / 4

• Where D is the diameter of the circular bar, L is the length of the bar, and ρ is the density of the material.

• Make sure to use consistent units for diameter, length, and density in the formula.

• For example, if the diameter of the circular bar is 10 mm, the length is 1 m, and the density of the material is 7850 kg/m^...read more
