Question

Unit of payment in MKS of beam is _____________

(a) per cu m

(b) cu m

(c) per sq ft

(d) per sq m

The question was asked in an interview for internship.

I'd like to ask this question from Arch Masonry Calculation topic in chapter Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing

Answer 1

Right answer is (a) per cu m

To explain I would say: A beam is a structural element that primarily resists loads applied laterally to the beam’s axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam’s support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material.
