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.

Asap

А теchanical component is
subjected to a normally distributed force with a
mean of 1000 N and a standard deviation of 200
N. The designer has used a factor of safety of 1.5

(ii) It is required to reduce the standard
deviation of part strength by better quality
control in order to achieve a failure rate
of only 1%. What should be the standard
deviation of the strength assuming other
factors without any change?
(iii) It is required to improve the mean strength
of the component by using better material in
order to achieve a failure rate of 1%. What
