where V and R are constants. Calculate all the stress components.
The stress components in the given velocity field are σᵣᵣ = -2μV/R, σₜₜ = -2μV/R, and σᵩᵩ = 0.
The stress components in a fluid flow can be determined using the Navier-Stokes equations and the constitutive relationship for a Newtonian fluid. In this case, the velocity components in spherical coordinates are provided.
The stress component σᵣᵣ represents the radial stress, which is the force per unit area acting perpendicular to a radial plane. It can be calculated using the formula σᵣᵣ = -μ(∂vᵣ/∂r + (1/r)(vᵩ/r) + (1/r)(∂vₜ/∂θ) + (vₜ/tanθ)). By substituting the given velocity components, we find σᵣᵣ = -2μV/R.
Similarly, the stress component σₜₜ represents the tangential stress, which is the force per unit area acting tangentially to a circular plane. It can be calculated using the formula σₜₜ = -μ[(1/r)(∂(rvₜ)/∂r) - (vₜ/r) + (1/r)(∂vᵩ/∂θ) - (vᵩ/tanθ)]. By substituting the given velocity components, we find σₜₜ = -2μV/R.
Finally, the stress component σᵩᵩ represents the azimuthal stress, which is the force per unit area acting in the azimuthal direction. In this case, the given velocity component vᵩ is zero, indicating that there is no flow in the azimuthal direction. Therefore, σᵩᵩ = 0.
In summary, the stress components in the given velocity field are σᵣᵣ = -2μV/R, σₜₜ = -2μV/R, and σᵩᵩ = 0. These stress components provide information about the distribution of forces within the fluid flow.

The injection molding department of a company that operates 24x7 uses an average of 34 gallons of special lubricant per day. The usage of lubricant is normally distributed with a standard deviation of 4.4 gallons per day and it takes 6.5 weeks for an order of lubricant to be delivered. If the largest service level is 73%, what is the reorder point?
The injection molding department of a company that operates 24x7 uses an average of 34 gallons of special lubricant per day. The usage of lubricant is normally distributed with a standard deviation of 4.4 gallons per day and it takes 6.5 weeks for an order of lubricant to be delivered. If the largest service level is 73% The reorder point for the injection molding department is approximately 1549.508 gallons.
To calculate the reorder point, we need to consider the lead time demand, which is the demand during the time it takes for a new order to be delivered.
Given that the injection molding department operates 24x7 and uses an average of 34 gallons of special lubricant per day, we can calculate the daily demand as 34 gallons.
Since the demand follows a normal distribution with a standard deviation of 4.4 gallons per day, we can use the Z-score formula to calculate the safety stock. The Z-score represents the number of standard deviations from the mean.
To determine the Z-score corresponding to a service level of 73%, we can use a Z-table or a statistical calculator. The Z-score for a 73% service level is approximately 0.57.
Next, we need to calculate the lead time demand. The lead time is given as 6.5 weeks, and since there are 7 days in a week, the lead time is equal to 6.5 x 7 = 45.5 days.
To calculate the lead time demand, we multiply the average daily demand by the lead time in days. Therefore, the lead time demand is 34 gallons/day x 45.5 days = 1547 gallons.
To calculate the reorder point, we add the lead time demand to the safety stock. The safety stock is given by the formula: Safety Stock = Z-score x standard deviation.
Using the given standard deviation of 4.4 gallons per day and the calculated Z-score of 0.57, the safety stock is 0.57 x 4.4 gallons/day = 2.508 gallons.
Finally, we can calculate the reorder point by adding the lead time demand to the safety stock: Reorder Point = Lead time demand + Safety stock.
Reorder Point = 1547 gallons + 2.508 gallons = 1549.508 gallons.

a common collector amplifier has a current gain of 201. determine the curren gains when the amplifier is common base and common emitter respectively derive any formula used
Current Gain when amplifier is common base and common emitter = -201 A
The formula used = IB+IE+IC=0
How to determine the Current gain?Think of current gain as the difference between the input and output current. The input current and output current in a common collector are the base current (IB and IE, respectively).
You should be able to determine all of this by using the formula IB+IE+IC=0, which states that the sum of all currents must be zero. Recognize that IE is negative if all currents are assumed to be positive entering the transistor; hence, the actual value of current gain is -201; nevertheless, we often just use the absolute amount.

F =
The force acting at the point (x, y) can be determined by finding the gradient of the potential energy function U = 3x^5y - 4x. The force vector that acts at the point (x, y) is given by F = (15x^4y - 4) * i + (3x^5) * j.
To find the force vector at the point (x, y) based on the given potential energy function U = 3x^5y - 4x, we need to calculate the gradient of the potential energy function. The gradient is a vector that points in the direction of the steepest increase of a scalar function and has components equal to the partial derivatives of the function with respect to each variable. In this case, the potential energy function U has two variables, x and y. Therefore, the force vector F can be obtained by taking the partial derivatives of U with respect to x and y and combining them into a vector. Let's calculate the force vector F:
First, find the partial derivative of U with respect to x:
∂U/∂x = 15x^4y - 4
Next, find the partial derivative of U with respect to y:
∂U/∂y = 3x^5
Now, construct the force vector F using these partial derivatives:
F = (∂U/∂x) * i + (∂U/∂y) * j
where i and j are the unit vectors along the x and y directions, respectively.
Substituting the partial derivatives, the force vector F is:
