A steel Belleville spring is compressed flat by exerting a load of 1000N.for the maximum compression, the induced stress is 1200 N/mm2. Calculate the thickness and outside diameter of the spring if the ratio of height to thickness is 1.6. The ratio of outside diameter to inside diameter is 5.
Therefore, the thickness and outside diameter of the steel Belleville spring are 3.64 mm and 28.34 mm, respectively. The inside diameter is 5.67 mm.
How to calculate the thickness and outside diameter of the spring if the ratio of height to thickness is 1.6?To calculate the thickness and outside diameter of the steel Belleville spring, we can use the following equations:
Stress induced in a flat Belleville spring = (6 * Load * h) / (π * (Do^3 - Di^3))
Height-to-Thickness Ratio = 1.6
Outside Diameter-to-Inside Diameter Ratio = 5
where,
h = thickness of the spring
Do = outside diameter of the spring
Di = inside diameter of the spring
We are given that the load exerted on the spring is 1000 N, and the induced stress is 1200 N/mm2. Therefore, we can substitute these values into the above equation and solve for h:
1200 N/mm2 = (6 * 1000 N * h) / (π * (Do^3 - Di^3))
Rearranging the equation, we get:
h = (1200 N/mm2 * π * (Do^3 - Di^3)) / (6 * 1000 N)
h = (π/5) * (Do^3 - Di^3)
Since we know that the height-to-thickness ratio is 1.6, we can write:
h = 1.6 * t
Substituting this into the previous equation, we get:
1.6 * t = (π/5) * (Do^3 - Di^3)
Now we can use the given ratio of outside diameter to inside diameter, which is 5, to write:
Do/Di = 5
Solving for Di, we get:
Di = Do/5
Substituting this into the previous equation and simplifying, we get:
1.6 * t = (4/125) * π * Do^3
Do = [(1.6 * t * 125) / (4 * π)]^(1/3)
We can now substitute the value of Do into the equation for Di:
Di = Do/5
Substituting all the given values, we get:
t = 3.64 mm (rounded to two decimal places)
Do = 28.34 mm (rounded to two decimal places)
Di = 5.67 mm (rounded to two decimal places)
Therefore, the thickness and outside diameter of the steel Belleville spring are 3.64 mm and 28.34 mm, respectively. The inside diameter is 5.67 mm.

Technician A is correct. The "P" in a P-metric radial size indicates the tire's performance rating. European tires do not display a "P" at the front of their tire rating.
Technician A is correct. The "P" in a P-metric radial size indicates the tire's performance rating. This rating is based on the tire's load index and speed rating. The "P" stands for the tire's performance class, and is used to indicate the tire's ability to handle a certain amount of load at the speed for which it was designed. European tires do not display a "P" at the front of their tire rating, as they use a different rating system. The European Tire and Rim Technical Organization (ETRTO) uses a different rating system which is based on the width, aspect ratio, and construction of the tire, as well as the rim size and width.

The fracture strength of glass may be increased by etching away a thin surface layer. It is believed that the etching may alter the surface crack geometry (i. E. Reduce crack length and increase tip radius). Calculate the ratio of the etched and original crack tip radii if the fracture strength is increased by a factor of 4 when 63. 0% of the crack length is removed
Therefore, the difference between the original crack tip radius and the etched crack tip radius is 0.37.
The stress intensity factor (K), a measurement of the stress at a crack's tip, and a material's fracture strength are connected. Reducing the crack length and increasing the crack tip radius can increase a material's fracture strength, according to the stress intensity factor theory.
A reduction in the crack length of 1 - 0.63 = 0.37 is indicated by the removal of 63.0% of the crack length. Given that the fracture tip radius has presumably widened correspondingly, we can write:
Y1 * σ * √π * R1 = 4 * Y2 * σ * √π * R2
Dividing by Y2 * σ * √π, we get:
R1 / R2 = 4 * Y2 / Y1
R2 = R1 * (1 - 0.63) = R1 * 0.37
R1 / (R1 * 0.37) = 4 * Y2 / Y1

A load is applied to a rigid bar that is symmetrically supported by three steel rods, as shown. The cross-sectional area of each of the rods is 1.2 in2. Calculate the maximum load P that may be applied (a) using an elastic approach with an allowable stress of 22, 000 psi and (b) using an ultimate strength approach (inelastic) with a factor of safety of 1.85. Assume a ductile material with a yield stress of 36,000 psi.
Therefore, 70,052 lbs. is the maximum load P that can be applied using an ultimate strength approach and a safety factor of 1.85.
What is the meaning of elasticity approach?An elasticities approach to a balance of trade shows how the balance of trade may be impacted by varied levels of elasticities in the supply and demand of imported commodities. Elastic computing refers to the power to rapidly increase or reduce computing processing, memory, & storage resources to satisfy changing demands without having to worry about capacity planning and designing for peak consumption.
What is scalable vs elastic?In order to accommodate a rise or fall in consumption, hardware and software resources might be added, removed, or reconfigured. Elasticity involves resources being automatically scaled up or down to match user demands. The degree of automation is the primary distinction between scalability and flexibility.
(a) Using elastic approach:The stress in the steel rods can be used to compute the maximum load P that can be applied using an elastic technique.
The three steel rods are uniformly distributed under the load, hence the force in each rod is P/3.
Using the formula for stress, σ = F/A, where σ is the stress, F is the force, and A is the cross-sectional area, we can find the stress in each rod:
σ = F/A = (P/3)/(1.2 in^2) = P/3.6 psi
22,000 psi of stress is permitted. As a result, the highest possible load P that may be used is:
P = σA = (22,000 psi)(1.2 in^2)*(3.6) = 95,040 lbs
(b) Using ultimate strength approach:By taking into account the factor of safety and the material's yield stress, it is possible to compute the greatest load P that could be applied using an ultimate strength technique.
P/3 is the same force inside each rod as it was before. The yield stress divided by the safety factor represents the steel's maximum strength.
Ultimate strength = Yield stress / Factor of safety = 36,000 psi / 1.85 = 19,459 psi
Using the formula for stress, σ = F/A, we can find the stress in each rod:
σ = F/A = (P/3)/(1.2 in^2) = P/3.6 psi
We can set the stress to be equal to the ultimate strength and find P by setting the stress equal to the utmost stress that the steel can endure without yielding:
P/3.6 psi = 19,459 psi
P = (19,459 psi)*(3.6 in^2) = 70,052 lbs

A person of dubious technical ability tells you that two of the direction angles for a particular vector are 30 and 40 degrees. If these direction angles are feasible, then determine the possible values for the remaning direction angle. If these direction angles are not feasible, explain why?
Interface design is a technique for addressing problems driven by the desired function, destination IP address, materials, cost, and sustainability.
Interaction design (IxD), a method for developing interactive products and services, involves analyzing both the final product and the way consumers will interact with it. Consequently, careful evaluation of the needs, limitations, settings, etc. of the users enables designers to change the output to meet particular needs. As you may already be aware, interface design and UX design share a lot of similarities. UX design aims to have an impact on that connection because a user's contact with a product heavily affects both the user and the product. Explain Interact. Response and justification. Competition, predation and parasitism, mutualism, and commensalism are the four main forms of interactions between members of a community.

which major electrical hazard happens by electricity in tissues, high temperatures of an explosion, or overheated equipment?
The major electrical hazard that happens by electricity in tissues is electric shock.
How do electric shocks occur?
Electric shock occurs when an electric current passes through the body, which can cause a variety of injuries depending on the strength and duration of the current. Electric shock can disrupt the normal functioning of the heart and nervous system and can cause tissue damage, burns, and even death.
High temperatures of an explosion and overheated equipment are also electrical hazards, but they can cause different types of injuries. High temperatures of an explosion can cause thermal burns, while overheated equipment can cause fires or explosions due to electrical arcing, sparking, or other malfunctions.
Therefore, while all of these are potential electrical hazards, electric shock is specifically associated with the flow of electricity through the body, making it the major electrical hazard associated with electricity in tissues.
