Answer:
4.8°C
Explanation:
The rate of heat transfer through the wall is given by:
Assumptions:
1) the system is at equilibrium
2) the heat transfer from foam side to interface and interface to block side is equal. There is no heat retention at any point
3) the external surface of the wall (concrete block side) is large enough that all heat is dissipated and there is no increase in temperature of the air on that side
temperature at the interface
Solving for will give the temperature at the interface:
Answer:
Shearing strain will be 0.1039 radian
Explanation:
We have given change in length
Length of the pad L = 1.15 inch
We have to find the shearing strain
Shearing strain is given by
Shearing strain is always in radian so we have to change angle in radian
So
