PART – A (8 x four = 32)
ans All the ques.

1. Draw neat sketch of Disc DOWELLED JOINT in timber.

2. What do you mean by Grading of timber?

3. Draw neat sketch of Madras Terrace Roof.

4. What are the design loads to be considered while designing Madras Terrace Wooden joist.

5. Define (i) Pitch and (ii) Gauge length of rivets.

6. List disadvantages of welded joints.

7. Define 'Laterally restrained beam' provide an example.

8. Under what circumstances are built-up beams resorted to?

PART – B (4 x 12 = 48)
ans All the ques.

9. A teak wood member 80mm x 240mm caries an axial pull of 40KN. Design a suitable disc- dowelled joint for the member.
(or)
10. Design simply supported deodar wood beam for the subsequent data.
Grade of timber: common, Location: Inside, Span: 4m Load udl: 15kN/m.

11. Design Madras terrace roof size 5m x 12m using standard grade teak wood.
(or)
12. What is the maximum span of a 50mm x 100mm timber joist of a Madras Terrace Roof with a total load of eight kPa if they are spaced at 600mm c/c distances? The permissible stresses in timber joist are 10.0 and 1.0 Mpa. Respectively in bending and shear. The permissible deflection and young's modules for the joist are span/360 and 105 x 104 Mpa respectively.

13. Design double cover butt joint ranging from 2 mild steel plate 320mm wide and 18 mm thick.
(or)
14. An angle 150 x 115 x 10mm carries an axial tension of 250kN. Design a suitable welded joint to connect it with a guest plate at its ends by welding the longer leg.

15. Design main floor beam supporting 3 equidistance floor joist over a span of 10m. every joist provides lateral restrain to main and transmits a load of 60kN on the main beam.
(or)
16. Determine the maximum imposed load that could be carried by an ISLB @ 569N/m when simply supported at its ends with an effective span of 8m, satisfying the strength and stiffness requirements.
Take sbc = sbt = 165N/mm2 and Cva = 100N/mm2
