Answer:
(a) Modified Goodman criterion:
Factor of safety against fatigue failure = 1.0529
(b) Gerber criterion:
Factor of safety against fatigue failure = 1.31
(c) ASME-elliptic criterion:
Factor of safety against fatigue failure = 1.315
Explanation:
See the attached file for the calculation.
Answer:
B) a kinetic friction
Explanation:
The force of friction in a movement object its called kinetic friction force (<em>fk). </em>The net force acting in the direction of the movement its express, according to the Newton second law, like this: F- <em>fk. </em>That expression says that the net force produces an aceleration in the direction of the movement of the object.
Now if the force its removed, the <em>fk</em> its continue acting in the object but now in the opposite direction. And according to the Newton second law this <em>fk </em>it going to continue acting until the object stay in a still state.
<u>In conclusion</u>, if an object moves in some direction the kinetic friction force always be opposite to that direction of movement, according to the Newton second law
Answer:
0.31 μm
Explanation:
this question wants us to Determine the depletion region width, xn, in the n-side in unit of μm. using the information below.
density in the p-side = 5.68x10^16
density in the n-side = 1.42x10^16
= √(1.42x10⁵)(1.76056335x10⁻¹⁷ + 7.042253521x10⁻¹⁷)(1.2)
= √150.74x10⁻¹¹
= 3.882x10⁻⁵
approximately 0.39μm
xn = 0.39 x 0.8
= 0.31μm
0.31 um is the depletion region width. thank you!
Answer:
Complete question is:
write the following decorators and apply them to a single function (applying multiple decorators to a single function):
1. The first decorator is called strong and has an inner function called wrapper. The purpose of this decorator is to add the html tags of <strong> and </strong> to the argument of the decorator. The return value of the wrapper should look like: return “<strong>” + func() + “</strong>”
2. The decorator will return the wrapper per usual.
3. The second decorator is called emphasis and has an inner function called wrapper. The purpose of this decorator is to add the html tags of <em> and </em> to the argument of the decorator similar to step 1. The return value of the wrapper should look like: return “<em>” + func() + “</em>.
4. Use the greetings() function in problem 1 as the decorated function that simply prints “Hello”.
5. Apply both decorators (by @ operator to greetings()).
6. Invoke the greetings() function and capture the result.
Code :
def strong_decorator(func):
def func_wrapper(name):
return "<strong>{0}</strong>".format(func(name))
return func_wrapper
def em_decorator(func):
def func_wrapper(name):
return "<em>{0}</em>".format(func(name))
return func_wrapper
@strong_decorator
@em_decorator
def Greetings(name):
return "{0}".format(name)
print(Greetings("Hello"))
