Merino Industries Site Engineer Interview Questions and Answers

SFD & BMD for a simply supported load

• SFD is a diagram that shows the variation of shear force along the length of a beam

• BMD is a diagram that shows the variation of bending moment along the length of a beam

• For a simply supported load, the SFD will be a straight line with a constant slope

• The BMD will be a parabolic curve with the maximum value at the center of the beam

• The SFD and BMD can be calculated using equations an

The density of steel and cement varies depending on the type and composition.

• The density of steel ranges from 7,750 to 8,050 kg/m³.

• The density of cement ranges from 1,100 to 1,500 kg/m³.

• Different types of steel and cement may have slightly different densities.

• Density is an important property to consider in construction and engineering calculations.

Cutting length of beam ring is the length of steel required to form a complete ring around the beam.

• The cutting length of beam ring is calculated by adding the circumference of the beam to twice the development length of the steel.

• The development length of the steel is the length required for the steel to fully bond with the concrete.

• The cutting length of beam ring is important for determining the amount of steel requi...read more
