If the thickness of plate to be connected by a rivet is 16 mm, then suitable size of rivet as per Unwin’s formula will be

As per Unwin’s formula, if t is the thickness of the plate in mm, what will be the nominal diameter of the rivet?

A

d = 6.04 $\sqrt t $

B

d = 6.04 t²

C

d = 6.04 t^2/3

D

d = 6.04 t^1/4

According to Unwin's formula, the relation between the diameter of rivet hole (d) and the thickness of plate (t) is given by (where d and t are in mm)

A

$${\text{d}} = \sqrt {\text{t}} $$

B

$${\text{d}} = 1.6\sqrt {\text{t}} $$

C

$${\text{d}} = 2\sqrt {\text{t}} $$

D

$${\text{d}} = 6\sqrt {\text{t}} $$

According to Unwin's formula, the relation between diameter of rivet hole (d) and thickness of plate (t) is given by (where d and t are in mm)

A

d = t

B

d = 1.6 t

C

d = 2t

D

d = 6t

Diameter of rivet hole (d, mm) and the plate thickness (t, mm) are related by Unwin's formula as

A

d = 1.1 t

B

d = 1.6$$\sqrt {\text{t}} $$

C

d = 1.5 t

D

d = 3$$\sqrt {\text{t}} $$

The nominal diameter (φ) of rivet (in mm units) using Unwin’s formula is given by which of the following options? Where t is the thickness of the steel plate (in mm unit)

A

$\varphi = 6.01\sqrt t $

B

$\varphi = 6.01\sqrt {2t} $

C

$\varphi = 8\sqrt t $

D

$\varphi = 6.01\sqrt {{t^2}} $

B

Is at the minimum distance from CG of the rivet group

C

Gives the maximum angle between the two forces Fa and Fm

D

Gives the minimum angle between the two forces Fa and Fm
