Answer:
Explanation:
We feel chilled in summer but comfortable in the summer under the same temperature because of our thermal comfort.
Thermal comfort is a function of heat loss from the body and during winter there is excessive heat loss due to heat flux.
As room temperature is fixed so summer and winter comfort cannot be attributed due to heat loss by convection. Due to differences in heat flux radiations in summer and winter there is a chilled feeling associated with winters.

Answer:
Engineering and the Engineering management
Explanation:
Systems engineering is a discovery process that includes managing and designing complex systems to formalize the various new research approach or methods.
It is an interdisciplinary holistic approach or field that is comprised of <u>engineering and the engineering management.</u>
The three types of systems engineering are: Product Systems Engineering, Enterprise Systems Engineering and Service Systems Engineering.
Answer:
Explanation:
The formula for critical stress is
K is the plane strain fracture toughness
Y is dimensionless parameters
We are to Determine the Critical stress
Now replacing the critical stress with 54.8
a with 0.2mm = 0.2 x 10⁻³
Y with 1
The fracture will not occur because this material can handle a stress of 2186.20Mpa before fracture. it is obvious that is greater than 2023Mpa
Therefore, the specimen does not failure for surface crack of 0.2mm
