Q1:

The intrinsic equation of catenary is

A S = c tan ψ

B y = c cosh x/c

C y = c cosh ψ

D y = c sinh ψ.

ANS:A - S = c tan ψ

The equation S=C tan⁡ ψ is not the intrinsic equation of the catenary curve. The correct intrinsic equation for the catenary curve is y=c cosh (X/C​), where y represents the vertical displacement, x represents the horizontal displacement, and c is a constant that determines the shape of the curve. The equation S=C tan ψ is not a standard equation used to describe the catenary curve. It seems to represent a different context or formula altogether.
