Answer:
option B.
Explanation:
The correct answer is option B.
Principal stress is the maximum normal stress a body can have. In principal stress, there is purely normal stress. On principal plane shear stress is zero.
In-plane shear stress are the shear stress which is acting on the plane.
The statement which is correct regarding principle plane and shear stress is that The shear stress over principal stress planes is always zero.
Answer:
the heat transfer from the pipe will decrease when the insulation is taken off for r₂< 
where;
r₂ = outer radius
= critical radius
Explanation:
Note that the critical radius of insulation depends on the thermal conductivity of the insulation k and the external convection heat transfer coefficient h .
The rate of heat transfer from the cylinder increases with the addition of insulation for outer radius less than critical radius (r₂< ) 0, and reaches a maximum when r₂ = , and starts to decrease for r₂< . Thus, insulating the pipe may actually increase the rate of heat transfer from the pipe instead of decreasing it when r₂< .
Answer: Vo= 39.84 volts
Explanation:
Let Vo to be the voltage level of the signal,
Therefore,
Vo = 120{0.5(0) + 0.25(1) + 0.125(0) + 0.0625 (1) + 0.03125(0)
+ 0.015625(1) + 0.007812(0) +0.003906(1)}
Vo= 39.84 volts
Answer:
Explanation:
Floor Load:
Lo= 50psf
At= 25x25 = 625 square feet
= 13.1psf
%reduction= 13.1/50 = 26%
Fr= 3[(13.1psf)(25ft)(25ft)+(20psf)(25ft)(25ft)]= 62k
Answer:
- TAX_RATE = 0.20
- STANDARD_DEDUCTION = 10000.0
- DEPENDENT_DEDUCTION = 3000.0
-
- # Request the inputs
- grossIncome = float(input("Enter the gross income: "))
- numDependents = int(input("Enter the number of dependents: "))
-
- # Compute the income tax
- taxableIncome = grossIncome - STANDARD_DEDUCTION - \
- DEPENDENT_DEDUCTION * numDependents
- incomeTax = taxableIncome * TAX_RATE
-
- # Display the income tax
- print("The income tax is $" + str(round(incomeTax,2)))
Explanation:
We can use round function to enable the program to output number with two digits of precision.
The round function will take two inputs, which is the value intended to be rounded and the number of digits of precision. If we set 2 as second input, the round function will round the incomeTax to two decimal places. The round function has to be enclosed within the str function so that the rounded value will be converted to a string and joined with the another string to display the complete a sentence of income tax info.
