Explain law of transmissibility of forces. Find the reactions at supports A and B of the loaded beam shown in Fig.
What are lacings and battens in a built-up column? Explain their functions. Explain the concept of shear lag in an angle tension member connected by only one leg and how it affects design strength calculation.
What do you mean by point of contra flexure? Is point of contra flexure and point of inflexion different? A horizontal beam AB of length 4 m is hinged at A and supported on rollers at B. The beam carries inclined loads of 100 N, 200 N and 300 N inclined at 60°, 45° and 30° to horizontal as shown in Fig. Draw shear force and bending moment diagram for the beam.
