35.
According to the Unwin's formula, if t is thickness of the plate in cm, the nominal diameter of the rivet, is
d = 1.91 t
d = 1.91 t2
d = 1.91 t
d = 1.91 t
d = 2.3 t

d=6.04√t where t is in mm.
When we change it in cm, 1 cm =10mm.
d=6.04√(t/10) = 1.91√t.

Correct answer is;

Unwin's formula =6√t.

6√t mm = 6√{t/10} cm = 1.9√t cm.

Thanks @Roy.

1.9√t for cm. 6.05√t is for t in mm.

If the thickness of the plate is in mm then the formula is 6.05√t and if the thickness is specified in cm then convert thickness mm to cm and this thickness is in the root.

So if we took root for this and multiple by 6.05 the we will get 1.91√t.

Well said, thanks @Roy.

6=d.01*√t, where t=thickness of the smaller plate.

@All.

First take square in both sides for easy calculation then convert units you will get the answer.
