Answer:

Explanation:

The idea of designing products with 100% performance while keeping the costs at only 10% is absurd and unrealistic.

Designing high-performance products requires investments in quality materials, advanced technologies, research and development, and skilled engineering expertise. These factors contribute to higher costs. Achieving such a drastic difference between performance and cost is not practically feasible.

Companies strive to find a balance between performance and cost by employing cost optimization strategies, value engineering, and efficiency improvements. They aim to maximize the performance-to-cost ratio but understand the inherent trade-offs involved.

While companies continuously work towards improving performance and reducing costs, it is crucial to have realistic expectations and understand the practical limitations of product design.

Layer 3 of the OSI (Open Systems Interconnection) model, known as the network layer, is responsible for providing end-to-end communication between hosts in different networks.

The network layer is responsible for routing and forwarding data packets across different networks, as well as handling addressing and logical connectivity.

The main entities that live at layer 3 (the network layer) of the OSI model include:

Routers: Routers are network devices that operate at the network layer and are responsible for forwarding data packets between different networks. They use routing tables and protocols to determine the best path for data packets to reach their destination across multiple networks.

IP (Internet Protocol): IP is a network layer protocol that provides logical addressing and routing functionality. It is responsible for assigning unique IP addresses to devices on a network, and for routing data packets based on those IP addresses.

ICMP (Internet Control Message Protocol): ICMP is a network layer protocol that is used for sending error messages and operational information about network conditions. It is often used for diagnostic purposes, such as ping and traceroute, to check the connectivity and status of network devices.

Network Addressing: Layer 3 is also responsible for assigning and managing IP addresses, which are used to uniquely identify devices on a network.

Subnetting and VLANs: Layer 3 may also involve subnetting and VLANs (Virtual Local Area Networks), which are used for network segmentation and management to improve efficiency and security.

The theoretical fracture strength of the brittle material is estimated to be approximately 165.6 MPa when a stress of 1300 MPa is applied and fracture occurs by the propagation of an elliptically shaped surface crack of length 0.29 mm and tip radius of curvature of 0.004 mm.

To estimate the theoretical fracture strength of a brittle material given the information provided, we can use Griffith's theory of brittle fracture. According to this theory, the fracture strength of a brittle material can be expressed as:

σ_f = (2Eγπa)^0.5

where σ_f is the fracture strength, E is the elastic modulus, γ is the surface energy per unit area, and a is the length of the elliptically shaped surface crack.

To calculate the fracture strength, we need to first determine the surface energy per unit area of the material. For glass, a typical value of surface energy is around 1 J/m^2.

Given the length of the elliptically shaped surface crack (a) is 0.29 mm, and the tip radius of curvature is 0.004 mm, we can calculate the crack area (A) as follows:

A = πab = π(0.29/2)(0.004)

A ≈ 5.67 x 10^-7 m^2

Next, we can calculate the elastic modulus (E) of the material. For glass, the elastic modulus is typically around 70 GPa.

Substituting these values into the equation for fracture strength, we get:

σ_f = (2Eγπa)^0.5 = [2(70 x 10^9)(1)(π)(0.29 x 10^-3)]^0.5

σ_f ≈ 165.6 MPa

Answer:

a. True

Explanation:

The study of fluids in a state of rest or in motion and the forces involved in it is called fluid mechanics. Fluid mechanics has a wide range of applications in the field of mechanical engineering as well as civil engineering.

When we study the flow of fluid between any two flat plates that is indefinitely flat and is parallel, the flow of the fluid is known as plane Poiseulle flow. The profile of a plane Poiseulle flow is parabolic.

The velocity profile of a plane Poiseulle flow is :

\($\frac{u(y)}{U_{max}}=1-\left(\frac{2y}{h}\right)^2$\)

Thus the answer is TRUE.

Given Data:

Internal pressure of tank = 90 psi

Internal diameter of tank = 22 in

Wall thickness = 0.25 in

Stress components are to be determined at point A and maximum shear is to be calculated.

Volume Element:

The volume element at point A has six faces and the stress components are acting on these faces. The stress components acting at point A need to be calculated.

Stress Components:

Consider the cylinder element shown below:

The stress acting on the horizontal and vertical faces is called longitudinal stress and the stress acting on the oblique faces is called shear stress.

Longitudinal Stress:

Longitudinal stress is given by the formula:

σL = (P x D) / (4t)

Where,

P is the internal pressure of the tank

D is the internal diameter of the tank

t is the thickness of the tank

Substituting the values in the formula, we get:

σL = (90 x 22) / (4 x 0.25)

σL = 1980 psi

Shear Stress:

The shear stress is given by the formula:

τ = σ / 2

Where,

σ is the longitudinal stress

Substituting the value of σ in the formula, we get:

τ = 1980 / 2

τ = 990 psi

The shear stress acting on the oblique faces is 990 psi and the maximum shear stress acting on the element is 990 psi. Hence, the maximum shear stress that this material would experience is 990 psi.

To archive a concentration of 40%, you need to add 62.5 kg of salt.

First, we have 150kg of aqueous salt solution with a concentration of the 15%, which means that the 15% of 150kg is salt, so we have:

0.15*150kg = 22.5 kg of salt.

Now we want to add a quantity M of salt, such that the new concentration of salt is of 40%.

The new mass of the mixture will be:

150kg + M

The new mass of salt will be:

22.5kg + M

The concentration of salt, in decimal form, will be:

(22.5kg + M)/(150kg + M)

The above quotient must be equal to 0.4 (40% in decimal form), then we solve:

(22.5kg + M)/(150kg + M) = 0.4

(22.5kg + M) = 0.4*(150kg + M)

(22.5kg + M) = 60kg + 0.4*M

M - 0.4*M = 60kg - 22.5kg

0.6*M = 37.5kg

M = (37.5 kg)/0.6 = 62.5kg

The formula for calculating gear speed is: (rpm of the driving gear * number of teeth on the driving gear) / number of teeth on the driven gear.

To calculate the speed of the spur gear, we can use the gear ratio formula, which is gear ratio = number of teeth on driven gear (spur gear) / number of teeth on driving gear (pinion gear).

In this case, the gear ratio is 42/14 = 3.

Next, we can use the formula for gear speed, which is gear speed = pinion gear speed / gear ratio.

Since the pinion gear is turning at 420 rpm, the gear speed of the spur gear is:

gear speed = 420 rpm / 3 = 140 rpm.

Therefore, the speed of the spur gear with 42 teeth driven by a pinion gear with 14 teeth turning at 420 rpm is 140 rpm.
