Mohr's circle method is used to obtain the principal stresses and their directions of a material sample which is undergoing two-dimensional stress.The values of normal stresses and shear stresses acting on the sample in two perpendicular directions are entered into a Mohr's circle diagram, as shown in the diagram below.
The circle's diameter is equal to the difference between the maximum and minimum principal stresses, and the circle's center is equal to the average of the two principal stresses. When the Mohr circle diagram is formed, the principal stresses and their directions can be obtained.In the case of plane stress, σ_z is equal to zero and the principal stresses can be found by using the following formula.σ_1+σ_2/2=±((σ_x-σ_y/2)²+τ_xy²)⁰⁵σ_1 and σ_2 are the two principal stresses, and τ_xy is the shear stress acting on the plane x-y. σ_x and σ_y are the stresses in the x and y directions, respectively.
Using the Mohr's circle method, find the principal stress and the orientation of the principal stress axes for the following case of plane stress: x=-1200MPa y=5000MPa and txy=-10000MPaWe can first draw the Mohr circle diagram, using the given values of x, y, and t_xy on the horizontal and vertical axis in a plane. Once the circle is drawn, we can use it to obtain the principal stresses and their orientation.
Now, let's apply the formula and calculate the principal stressesσ_1+σ_2/2=±((σ_x-σ_y/2)²+τ_xy²)⁰⁵σ_1+σ_2/2=±(((-1200)-5000/2)²+(-10000)²)⁰⁵σ_1+σ_2/2=±(17776450)⁰⁵σ_1+σ_2/2=±2112.18σ_1=2538.09MPaσ_2=-838.09MPaThe positive sign refers to the maximum principal stress, σ1, while the negative sign refers to the minimum principal stress, σ2.
The orientation of the principal axes can also be calculated using the following formula.θ_p=1/2 tan⁻¹((2τ_xy)/(σ_x-σ_y))θ_p=1/2 tan⁻¹((2(-10000))/((-1200)-5000))θ_p=-66.96° and 113.04°The orientation of the principal stress axis is -66.96° and 113.04° to the x-axis, respectively.To sum up, the maximum principal stress is σ1 = 2538.09 MPa, while the minimum principal stress is σ2 = -838.09 MPa. The orientation of the principal stress axis is -66.96° and 113.04° to the x-axis, respectively.

Each resistor has a resistance of 80 kN. What is the equivalent resistance of the resistive network shown? Reg = number (rtol=0.01, atol=1e-05) kOhms
The resistive network's equivalent resistance is 120k Ohms.
What is the comparable formula?We apply the equation Eq = MW / n to determine the Gram Equivalent Weight. Here, we'll discover how to determine a compound's equivalent weight formula. If a chemical entity has a mass of g grammes, then the mass supplied contains the gramme equivalents determined by the valency factor moles.
We can utilise the approach of connecting resistors in series and parallel to determine the equivalent resistance of the resistive network. We can connect the two resistors in parallel starting from the circuit's right side:
1/Rp = 1/80k + 1/80k
1/Rp = 1/40k
Rp = 40k Ohms
Next, we can connect the 80k resistor and 40k resistor in series:
R = 80k + 40k
R = 120k Ohms
The resistive network's equivalent resistance is 120k Ohms as a result.

The section is experiencing a positive bending moment about the z-axis, where Mz = 1.13 kN-m. What is the resulting stress at the top and bottom surfaces? And are they in tension or compression?
The resulting stress at the top and bottom surfaces is 837.5 N/m^2 and -837.5 N/m^2, respectively. The top surface is in compression and the bottom surface is in tension.
What is stress?
Stress in engineering is the amount of force per unit area placed on a material or structure. It can be physical, or it can be psychological. Stress can be positive or negative. Positive stress can cause a material to become stronger, while negative stress can cause it to become weaker or even fail. Stress can also refer to the amount of strain a material must endure before it yields or breaks. Stress is measured in terms of pounds per square inch (psi) or newtons per square meter (N/m2). Stress analysis is important in engineering as it helps to identify potential failure points in a design, or to determine how much a material can handle before it breaks. Stress analysis is used to ensure the safety and integrity of products, structures, and machines.

consider a stokes flow due to a sphere rotating near a wall, argue from kinematic reversibility weather or not the rotating sphere will experience a force pushing it away or drawing it into the wall
In Stokes flow, the fluid velocity is proportional to the forces acting on the fluid and the fluid is assumed to be viscous and incompressible. The fluid velocity near a rotating sphere in Stokes flow can be determined using the equations of fluid dynamics.
What is the reversibility about?Kinematic reversibility is a property of Stokes flow, which states that the fluid flow is symmetric with respect to time reversal. This means that if the fluid velocity is recorded at a certain time, then the same velocity field will be obtained if time is reversed and the flow is replayed in the reverse direction.
When a sphere is rotating near a wall, the flow of fluid around the sphere creates a velocity field that pushes the sphere away from the wall. This flow can be considered as the fluid being pushed away from the sphere and towards the wall. If the flow is time-reversed, the fluid velocity field would be the same, but the direction of the velocity would be reversed. This means that the fluid would be drawn towards the sphere and away from the wall, pulling the sphere towards the wall.
Therefore, based on the property of kinematic reversibility in Stokes flow, the rotating sphere near a wall will experience a force that could either push it away from the wall or draw it towards the wall, depending on the direction of the flow.

The company advertises that ""green power"" is available in 145 kWh blocks for an additional $3.50 per month. (green power is generated from solar, wind power and methane sources.) If a certain customer uses an average of 400 kWh per month and commits to one monthly 150 kWh block of green power, what is her annual power bills?
What is the average cost per kWh with green power during the year? why does green power cost more than conventional power?
The annual power bill for this customer would be $1,076. This includes the cost of 400 kWh per month at $0.08 per kWh, plus 12 monthly blocks of 145 kWh green power at an additional cost of $3.50 per month.
The average cost per kWh with green power during the year would be $0.087 per kWh. This is calculated by the sum of monthly cost of 400 kWh at $0.08 per kWh, plus the 12 monthly blocks of 145 kWh green power at an additional cost of $3.50 per month, and dividing by the total number of kilowatt-hours used during the year (400 + 145 = 545).
There are a few factors that could make green energy more expensive than traditional energy. First, compared to conventional power, the infrastructure for producing and delivering green energy is frequently more expensive. Second, suppliers can charge more since there is frequently a greater demand for green energy than for conventional energy.

Answer:
Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing.
The operation of rebound hammer is shown in the fig.1. When the plunger of rebound hammer is pressed against the surface of concrete, a spring controlled mass with a constant energy is made to hit concrete surface to rebound back. The extent of rebound, which is a measure of surface hardness, is measured on a graduated scale. This measured value is designated as Rebound Number (rebound index). A concrete with low strength and low stiffness will absorb more energy to yield in a lower rebound value.

A food warmer made of thermo-plastic material is at 40°C and the surrounding environment is at 20°C. Calculate the rate of heat transfer per unit area of the surface,provided the surface is 20mm thick and the thermal conductivity of the material is 29W/m
Answer: 870 W/m²
Explanation:
Using Fourier's Law of Heat Conduction, the rate of heat transfer per unit area (q) can be calculated as:
q = k × (T1 - T2) / L
where k is the thermal conductivity of the material, T1 is the temperature of the warmer, T2 is the temperature of the surrounding environment, and L is the thickness of the material.
Plugging in the given values, we get:
q = 29 W/m·K × (40°C - 20°C) / (20 mm / 1000)
q = 870 W/m²
Therefore, the rate of heat transfer per unit area of the surface is 870 W/m².
