Steel

The centre to centre distance of rivets of adjacent rows measured in the direction of stress is

• Gauge

• Pitch

• Cover

• Edge distance

Types of failure in tension member

• Gross section yielding

• Net section rupture

• Block shear failure

Which of the following are correct 

where, d' = diameter of bolt hole in mm
d= nominal diameter of bolt in mm

•  $d'=d+1mm\ \left(\ d\ <14mm\right)$  

•  $d'=d+3mm\ \left(\ d\ >24mm\right)$  

•  $d'=d+2mm\ \left(\ 16<d\ <24mm\right)$  

•  $d'=d+2mm\ \left(\ 16\le d\ \le24mm\right)$  

In a steel plate with bolted connections, the rupture of the net section is a mode of failure under

• Tension

• Compression

• Shear

• Flexural

The slenderness ratio of the lacing bars under compression should not exceed

• 180

• 200

• 100

• 145

Recommended value of the effective length of a steel compression member effectively held in position and restrained against rotation is

• 1

• 0.8

• 0.65

• $\frac{1}{\sqrt{2}}$

Consider the following statement:

Two plates 10mm and 8mm thick are joined by a triple-riveted lap joint. What would be the minimum diameter of the rivet is calculated by the equation

 $d=6.04\sqrt{t}$  called Unwin's Formula
Which of the following statement is correct?

• t should be in mm

• d obtained will be in cm

• t should be in cm

• 'd' should not be less than 't' in any case

Effective throat thickness of a right angle fillet weld of leg length 10mm

• 7mm

• 5.5mm

• 6mm

• 5mm

In eccentric bolted connections the resultant force in each bolt is calculated by the equation 

 $\sqrt{F_1^2+F_{2^{ }}^2+2F_1F_2\cos\theta}$  
F1 and F2

• Shear force due to eccentricity

• Bending moment due to eccentricity

• Shear force due to vertical load

• Bending moment due to vertical load

ISMB 200 @ 40

200 and 40 are respectively

• Depth of web in mm, Weight per beam

• Width of the flange in mm, Weight per length

• Depth of web in mm, Weight per length

• Width of the flange in mm, Weight per beam
