a single crystal of iron (bcc) is pulled in tension at room temperature along the [120] direction. a) determine the schmid factor for all slip systems. be sure to show how you confirmed which combinations of planes and directions are valid slip systems b) what is the tensile stress at which this crystal will flow plastically
Answers
(a) To determine the Schmid factor for all slip systems in a single crystal of iron (bcc) pulled in tension along the [120] direction, we need to consider the valid slip systems and their corresponding Schmid factors.
In bcc crystals, slip occurs on specific slip systems characterized by a combination of crystallographic planes and directions. The valid slip systems in iron (bcc) include {110}<111>, {112}<111>, and {123}<111>.
To calculate the Schmid factor for each slip system, we need to determine the dot product between the slip direction and the applied tensile stress direction, as well as the dot product between the slip plane normal and the tensile stress direction.
For example, for the {110}<111> slip system:
Slip direction: [110]
Slip plane normal: [111]
Tensile stress direction: [120]
Schmid factor = (Dot product of slip direction and tensile stress direction) * (Dot product of slip plane normal and tensile stress direction)
By calculating the dot products for each slip system and applying the formula, we can determine the Schmid factors.
(b) The tensile stress at which the crystal will flow plastically depends on the critical resolved shear stress (CRSS) for the slip system with the highest Schmid factor. The CRSS represents the stress required to initiate slip in a particular slip system.
Once we identify the slip system with the highest Schmid factor, the corresponding CRSS value can be obtained from experimental data or material properties. The tensile stress at which plastic flow will occur is equal to or greater than the CRSS for that slip system.
It's important to note that the exact values for Schmid factors, CRSS, and the tensile stress required for plastic flow can vary depending on the specific crystallographic orientation and material properties of the iron (bcc) single crystal.

Here are some sample runs.
Enter the coordinates for the three points p0,p1,p2: 3.4, 2, 6.5, 9.5, -5.4
p2 is on the left side of the line from p0 to p1

def onTheLineSegement(x0,y0, x1,y1,x2,y2):
Answers
Here's a program that prompts the user to enter the coordinates for the three points p0, p1, and p2, and then uses the functions leftOfTheLine, OnTheSameLine, and onTheLineSegment to determine whether p2 is on the left side of the line from p0 to p1, on the same line, or on the right side of the line:
Python
# Define functions
def leftOfTheLine(x0, y0, x1, y1, x2, y2):
return ((x1 - x0) * (y2 - y0) - (x2 - x0) * (y1 - y0)) > 0
def onTheSameLine(x0, y0, x1, y1, x2, y2):
return ((x1 - x0) * (y2 - y0) - (x2 - x0) * (y1 - y0)) == 0
def onTheLineSegment(x0, y0, x1, y1, x2, y2):
return (min(x0, x1) <= x2 <= max(x0, x1) and
min(y0, y1) <= y2 <= max(y0, y1))
# Prompt the user to enter coordinates for p0, p1, and p2
x0, y0, x1, y1, x2, y2 = map(float, input("Enter the coordinates for the three points p0, p1, p2: ").split(','))
# Determine the position of p2 relative to the line from p0 to p1
if onTheSameLine(x0, y0, x1, y1, x2, y2):
print("p2 is on the same line as the line from p0 to p1")
elif leftOfTheLine(x0, y0, x1, y1, x2, y2):
print("p2 is on the left side of the line from p0 to p1")
else:
print("p2 is on the right side of the line from p0 to p1")
The program first defines the functions leftOfTheLine, onTheSameLine, and onTheLineSegment.
The leftOfTheLine function returns True if the point (x2, y2) is on the left side of the directed line from (x0, y0) to (x1, y1), the onTheSameLine function returns True if the point (x2, y2) is on the same line from (x0, y0) to (x1, y1), and the onTheLineSegment function returns True if the point (x2, y2) is on the line segment from (x0, y0) to (x1, y1).
The program then prompts the user to enter the coordinates for p0, p1, and p2, and uses the map function to convert the input to floats.
Finally, the program determines the position of p2 relative to the line from p0 to p1 using the onTheSameLine, leftOfTheLine, and onTheLineSegment functions, and prints the appropriate message.
The program first checks if p2 is on the same line as the line from p0 to p1, then checks if p2 is on the left side of the line, and finally, if p2 is not on the left side or the same line, it concludes that p2 must be on the right.

Answers
The method used to infer the rotations of models in a tree-structured parent/child hierarchy when the position of a leaf-node child is set is called "forward kinematics."
Forward kinematics is a technique used in computer graphics and robotics to determine the positions and orientations of interconnected objects in a hierarchical structure. In the context of a tree-structured parent/child hierarchy, it involves propagating transformations from the root to the leaf nodes. When the position of a leaf-node child is set, forward kinematics calculates the rotations of the parent and other intermediate nodes in order to maintain the desired position of the leaf node. This technique is essential for animating and manipulating complex 3D models and characters, allowing for realistic movements and interactions in virtual environments.

at what stage in a turbine engine are gas pressures the greatest? group of answer choices compressor inlet. turbine outlet. compressor outlet.
Answers
In a turbine engine, gas pressures are greatest at the turbine outlet stage.
A turbine engine is a type of internal combustion engine that uses the reaction principle of air propulsion. The basic operation of a turbine engine is the same as that of a jet engine. The air flowing into the engine is compressed and mixed with fuel, and then it is ignited and burned. The burning gases are expanded in a turbine, which drives a compressor or a propeller.The gas pressures are the highest at the turbine outlet stage in a turbine engine. At the turbine outlet, the combustion gas's energy is transferred to the turbine blades. The energy from the combustion gases drives the turbine blades, which causes the engine to produce thrust. The turbine outlet is where the combustion gases have the lowest pressure, so the energy transfer between the gas and the turbine blade is at its highest.

Total time taken = 0.769 hour
Explanation:
using the velocity method
for sheet flow ;
Tt = \(\frac{0.007(nl)^{0.8} }{(Pl)^{5}s^{0.4} }\)
Tt = travel time
n = manning CaH
Pl = 25years
L = how length ( ft )
s = slope
For Location ( 1 )
s = 0.045
L = 1000 ft
n = 0.06 ( from manning's coefficient table )
Tt1 = 0.128 hour
For Location ( 2 )
s = 2.5 %
L= 750
n = 0.13
Tt2 = 0.239 hour
For Location ( 3 )
s = 1.5%
L = 500 ft
n = 0.15
Tt3 = 0.237 hour
For Location (4)
s = 0.5 %
L = 250 ft
n = 0.011
Tt4 = 0.165 hour
hence the Total time taken = Tt1 + Tt2 + Tt3 + Tt4
= 0.128 + 0.239 + 0.237 + 0.165 = 0.769 hour
There are two methods you can use to check the crankshaft for straightness: __________.
Answers
There are two methods you can use to check the crankshaft for straightness visual inspection and measuring with a straightedge.
Visual inspection involves examining the crankshaft for any obvious signs of bending or warping. Look for visible cracks, bends, or uneven surfaces. If you notice any irregularities, it may indicate a problem with the straightness of the crankshaft.
The second method is measuring with a straightedge. Place a straightedge along the length of the crankshaft and check for any gaps between the straightedge and the crankshaft. If there are gaps, it suggests that the crankshaft is not straight.
Both methods are important in determining the straightness of the crankshaft. Visual inspection can give you a quick indication of any visible issues, while using a straightedge provides a more precise measurement. Remember to use the appropriate tools and follow proper safety precautions when conducting these checks.
