A steel elevator cable supports a load of 900 kg. The cable has a diameter of 2 cm and an initial length of 24 m. Find the stress and the strain of the cable and the amount it stretches under the load.
Answers
The stress and the strain of the cable and the amount it stretches under the load.
What is stress?
Stress is a natural response to life events that causes physical, emotional, and mental strain. It is the body’s way of responding to any kind of demand or threat. When a person experiences stress, their body releases hormones such as adrenaline and cortisol in order to help them respond to the challenge. This can cause a range of physical and mental effects, including increased heart rate, increased alertness, and a heightened state of awareness. Stress can be both positive and negative. Positive stress can help people stay focused and motivated, while negative stress can lead to feeling overwhelmed and anxious. It is important to find ways to manage stress in order to maintain physical and mental health. This can include healthy lifestyle habits such as regular exercise, social activities, and relaxation techniques like yoga and meditation. Additionally, talking to friends, family, or a mental health professional can help to reduce the impact of stress.
The stress, σ, in a cable is given by the equation:
σ = F/A
where F is the force the cable is supporting and A is the cross-sectional area of the cable. In this case, the force is 900 kg, or 9,000 N, and the cross-sectional area is πr2, where r is the radius of the cable. The radius of a 2 cm diameter cable is 1 cm, so the cross-sectional area is π(0.01)2 = 0.000314 m2.
Therefore, the stress in the cable is 9,000 N/0.000314 m2 = 28,621 N/m2.
The strain, ε, in a cable is given by the equation:
ε = ΔL/L
Where ΔL is the change in the length of the cable and L is the original length. In this case, the original length is 24 m and the amount the cable stretches under the load is ΔL = 900 kg × 9.81 m/s2 × 24 m = 21,216 kg m/s2.
Therefore, the strain in the cable is 21,216 kg m/s2/24 m = 884 kg m/s2.
Finally, the amount the cable stretches under the load is ΔL = 900 kg × 9.81 m/s2 × 24 m = 21,216 kg m/s2.

true or false a second -degree burn may develop blisters
Answers
True. A second-degree burn can indeed develop blisters.
Second-degree burns are characterized by damage to both the outer layer of skin (epidermis) and the layer beneath it (dermis).
Blisters can form as a result of the burn, with the damaged skin producing fluid-filled pockets. Blisters in second-degree burns are often painful and can be a characteristic sign of this type of burn.
Third-degree burns are less painful than second-degree burns because third-degree burns result in nerve damage, which reduces feeling.

Electric motors are mechanical energy converters that typically produce rotating motion from electrical energy. They can be summed up as machines that produce motive power through the usage of electricity.
What is electric motor?Electric motors not only offer a straightforward and effective way to produce high levels of drive output, but they are also simple to scale down, making it possible to incorporate them into other pieces of machinery and equipment. They are used in a wide range of applications in both industry and daily life as a result.
Among the many 19th-century scientists who contributed to the creation and advancement of electric motors, the British scientist Michael Faraday is acknowledged as having had a particularly significant impact. Faraday carried out a successful experiment in 1821 in which he used a magnet and a magnetic field produced by an electric current to turn a wire.

Compare and contrast cable-stayed and suspension bridges.
Answers
Answer:
Explanation:
They may look similar as both have cables, towers and roadway underneath. But the key difference in a cable-stayed bridge and suspension bridge is the way cables are tied to a tower.
In a cable-stayed bridge, the cables are tied and secured directly onto the tower. So the weight of roadway and vehicles are carried directly through cables by the towers.
In a suspension bridge, the suspension cables ride on the tower. They are not secured at the towers but instead are tied at both ends of the bridge. The weight of roadway and vehicles are carried through vertical suspenders onto the suspension cables.

Answers
Note that where Technician A says an automotive brake booster is a piston-type pump that develops pressure for the vehicles brake system, and Technician B says an automotive brake booster is a vacuum-operated device that assists brake pedal application, BOTH technicians are right.
What is the rationale for the above response?As Technician B describes, a vacuum-assisted brake booster uses engine vacuum to aid the brake pedal. The vacuum is created by the intake manifold of the engine and is utilized to power a diaphragm within the brake booster. When the driver pushes the brake pedal, the vacuum is activated to increase the pressure on the brake master cylinder, making it simpler for the driver to apply the brakes.
A hydraulic-assisted brake booster, as described by Technician A, employs a piston-type pump to provide pressure for the vehicle's braking system.

The wire electrode is fed through a welding gun, and an electrical arc is created between the wire and the workpiece. As the wire melts, it forms a pool of molten metal that cools to form a strong weld.
Therefore, this welding process is often used to manufacture a wide range of items, such as:
