Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Question

ASAP

A force F, (=20 N) is applied on an area A,
(=0.1 cm) at the surface of a fluid element in the outward
direction. The force F, acts at an angle of 60r from the
tangential plane at the point of application of the force.
Another force F, (=60 N) is applied in the same manner as
the foree F,, on an another area A, (=0.2 cm2) at the surface
of the same fluid element. The ratio of the normal stress at
area A, to the shear stress at årea 4, is
(A) 2:3
(B) 2:3/3
(C) 2:3
(D) 1:3
