Current can be calculated using the formula: Current (A) = Power (kW) / (sqrt(3) x Voltage (V) x Power Factor)

• Use the formula: Current (A) = Power (kW) / (sqrt(3) x Voltage (V) x Power Factor)

• Make sure to convert kW to W if necessary (1 kW = 1000 W)

• Ensure the power factor is a decimal value, not a percentage (e.g. 0.85 instead of 85%)

Point of contraflexure is the location in a beam where the bending moment changes sign.

• Point of contraflexure is where the bending moment is zero.

• It is the point where the beam changes from sagging to hogging or vice versa.

• It is typically located at a support or a point of concentrated load.

• Example: In a simply supported beam with a uniformly distributed load, the point of contraflexure is at the center.

BIM stands for Building Information Modeling, a digital representation of a building's physical and functional characteristics.

Shear force and bending moment diagrams show the variation of internal forces along a beam.

• Shear force is the force perpendicular to the beam's longitudinal axis.

• Bending moment is the moment that causes a beam to bend.

• Shear force diagram shows the variation of shear force along the length of the beam.

• Bending moment diagram shows the variation of bending moment along the length of the beam.
