The difference between the engineering design process and the reverse engineering process are there, but very subtle. The engineering design process is a process based on careful planning and months of designing to create a blueprint for a certain project. The reverse engineering process is the base of learning to create something by working backwards on a previously made inspiration for your project. Three differences are that that the engineering design process doesn't require any physical learning and is more based on mental and written learning (unlike the reverse engineering process). Another difference includes that in the reverse engineering process you don't need to take anything apart and learn how things work based on the on hands aspect of this variety of engineering. The final difference is that the engineering design project is made fresh from your own thoughts and not based off of a similar project.
Answer:
a) Thermal conductivity of skin: 
b) Temperature of interface: 
Heat flux through skin: 
Explanation:
a)

Where:
is thermal conductivity of a material,
is heat flux through a material,
is the thickness of the material,
is the temperature on the first side and
is the temperature on the second side




b)



The heat flux between both surfaces is constant, assuming the temperature is maintained at each surface.









Answer:
See explanation for step by step procedure to get answer.
Explanation:
Given that:
The conveyor belt is moving downward at 4 m>s. If the coefficient of static friction between the conveyor and the 15-kg package B is ms = 0.8, determine the shortest time the belt can stop so that the package does not slide on the belt.
