Situation 1 | A built-up beam made from fastening two channels to a wide flange section carries loads' as shown. The fasteners are 12mmØ bolts with allowable shear stress t= 110 MPa. For bearing, Ob= 220MPA for single shear, and ob= 275 MPa for double shear. E=200 GPA. Fy=420 МРа. 16 KN/m 10 KN/m A B D. IE 4m 1.35m 3.15m 1.5m 210mm 180mm 12mm 9mm 180mm 210mm 238mm 90mm

There are various practical applications of the concept of moments, like a rotation of the crank due to linear motion of the piston, the moment of inertia and its use in designing beams and columns, bending moment concept, torque, twisting moment, etc.
