200-mm lever and a 240-mm-diameter pulley are welded to the axle BE that is supported by bearings at C and D. If a 720-N vertical load is applied at A when the lever is horizontal, determine (a) the tension in the cord, (b) the reactions at C and D. Assume that the bearing at D does not exert any axial thrust.
Answers
Answer:
a) the tension in the cord T is 1200 N
b)
reaction at C along x-axis Cy is 400 N
reaction at C along y-axis Cy is 1200 N
reaction at C along z-axis Cz is 0 N
reaction at D along X-axis Dx is 1600 N
reaction at D along y-axis Dy is -480 N
Explanation:
a)
to find the tension in the cord, we say;
∑ Mz = 0
720(200) - T(120) = 0
144000 - 120T = 0
T = 144000/120
T = 1200 N
the tension in the cord T is 1200 N
b)
the reactions at C and D. Assume that the bearing at D does not exert any axial thrust.
we make use of the moment law of equilibrium at point D about y-axis.
∑ MDy = 0
Cx(120) - T(40) = 0
we substitute value of T
Cx(120) - 1200(40) = 0
Cx 120 = 48000
Cx = 48000/120
Cx = 400 N
reaction at C along x-axis Cy is 400 N
Next we also apply the moment law of equilibrium at point D about x-axis.
∑MD z = 0
-Cy(120) + 720(80 + 120) = 0
-Cy(120) = - 144000
Cy = -144000 / - 120
Cy = 1200 N
reaction at C along y-axis Cy is 1200 N
we also apply the force law of equilibrium along z direction
∑Fz = 0
Cz = 0 N
reaction at C along z-axis Cz is 0 N
we also apply the force law of equilibrium along x direction
∑Fx = 0
Cx + Dx + T = 0
Substitute 400N for Cx and 1200 N for Dx
so
400 + Dx + 1200 = 0
Dx = 1600 N
therefore reaction at D along X-axis Dx is 1600 N
we also apply the force law of equilibrium along y direction
∑ Fy = 0
Cy + Dy - 720 = 0
we substitute Cy = 1200 N
so
1200 + Dy - 720 = 0
Dy = - 480 N
therefore reaction at D along y-axis Dy is -480 N

A heat engine is a device able to transform work into heat.
a. True
b. False
Answers
Answer:
Option B: False
Explanation:
A heat engine is a device which operates in a manner that heat is converted into mechanical work.
A simple example of a heat engine is a drinking bird. The oscillatory motion of the drinking bird is as a result of the thermal expansion and contraction of a chemical compound in its beak, which creates an imbalance in its position of equilibrium. This causes it to oscillate.
Heat engines usually work by extracting heat once there is a temperature gradient available in the system and using it to perform work. Another good example is the internal combustion engine. It extracts heat from the explosion of the burning fuels and uses it to power the car.
how does the sound design of the opening scene in once upon a time in the west (1968) function?
Answers
The sound design of the opening scene in once upon a time in the west (1968) functions comprises of the elements of ambience and atmosphere, natural sounds, use of silence, musical score, sparsity of dialogue, sound effects, and contrasts and juxtapositions.
The opening scene of "Once Upon a Time in the West" (1968), directed by Sergio Leone, is a masterclass in sound design and effectively sets the tone for the entire film. Here's an analysis of how the sound design functions in that scene:
Ambience and Atmosphere: The scene begins with a vast, desolate landscape, and the sound design emphasizes the emptiness and isolation. The sound of a distant wind blowing, combined with the sparse sounds of nature like birds and insects, creates a sense of vastness and solitudeNatural Sounds: As the scene progresses, natural sounds are heightened to create tension and build anticipation. The buzzing of flies and the creaking of a windmill contribute to the overall atmosphere. These sounds are amplified, emphasizing their presence and creating a sense of discomfortUse of Silence: The sound design often utilizes silence strategically. In the opening scene, there are moments where the soundscape is completely silent, adding to the tension and allowing the viewer to focus on small details and subtle sounds that may occurMusical Score: Ennio Morricone's iconic score plays a vital role in the sound design. The score, particularly the haunting harmonica melody, serves as a character in itself. It intensifies the mood, adds emotional depth, and signifies the impending danger. The score's interplay with other sound elements creates a powerful audio experienceSparsity of Dialogue: In the opening scene, dialogue is minimal. This absence of conversation allows the sound design to take center stage. The lack of words places more emphasis on the ambient sounds, making them more pronounced and impactfulSound Effects: The sound design incorporates various diegetic sounds to enhance the realism and immerse the audience in the environment. For example, the sound of footsteps in the dirt, the creaking of a wooden floorboard, or the clinking of spurs, all contribute to the authenticity of the sceneContrasts and Juxtapositions: The sound design creates contrasts and juxtapositions to heighten the dramatic impact. For instance, the peaceful sounds of nature are abruptly interrupted by the jarring sounds of a train's arrival, accompanied by the thunderous noise of the steam engine. This stark contrast creates a sense of disruption and impending danger.Overall, the sound design of the opening scene in "Once Upon a Time in the West" functions to establish the film's atmosphere, convey emotions, build tension, and immerse the audience in the world Leone creates. It showcases a meticulous attention to detail and demonstrates the power of sound in storytelling.

Answers
A flow is considered laminar if the Reynolds number is up to 2300.
What is critical Reynold number?Laminar or turbulent fluid flow dynamics are described by the Reynolds number. Laminar flows have a lower Reynolds number, while turbulent flows have a higher Reynolds number. A key Reynold number, which is discussed in the following section, separates these two regimes. As the fluid flow rate rises, a system's transition from laminar to turbulent flow can be determined using the critical Reynolds number. For many enclosed systems, there isn't a single crucial Reynolds number; instead, it typically falls within a wide range between around 2300 and 4000.For enclosed systems, laminar flow typically occurs at about 2300 Reynolds numbers, while the essential Reynolds number in other systems can be very different.A flow is considered laminar if the Reynolds number is up to 2300.

A structural component is fabricated from an alloy that has a plane-strain fracture toughness of 62 MPa√m. It has been determined that this component fails at a stress of 250 MPa when the maximum length of an internal crack is 1.6 mm. What is the maximum allowable internal crack length (in mm) without fracture for this same component exposed to a stress of 250 MPa and made from another alloy that has a plane strain fracture toughness of 40 MPa√m?
Answers
Answer:
0.67 mm
Explanation:
Solution:
We find the dimensionless parameters by applying the critical stress crack propagation formula stated below:
σс= Klc/Y√πa
Y = Klc/σс √πa
σс = this is the critical stress needed for initial cracking propagation
Klc = the plain stress fracture toughness
a = surface length of the crack
Y = the dimensionless parameter
Now, we substitute the values 62MPa√m for Klc, 250 MPa for σс and 1.6 * 10 ^⁻3 for a in the dimensionless parameter equation.
Thus,
Y = Klc/σс √πa
= 62/250(√π * 1.6* 10 ^⁻3)
= 3.492
The next step is to find the maximum permitted surface crack length by applying the critical stress crack propagation equation given below:
σс= Klc/Y√πa
a= 1/π (Klc/Yσс)²
Now, substitute 40 MPa√m for Klc, 250 MPa for σс and 3.492 for surface length crack equation
So,
a= 1/π (Klc/Yσс)²
= 1/π[40/3.492 * 250]²
=1/π[40/873]²
=1/π[0.0458]²
0.318[0.0458]²
=0.318[0.00209]
= 0.0066
0.67* 10 ^⁻3 m
= 0.67 mm
Therefore the maximum surface crack length produced is 0.67 mm
