Mechanics

Torque on a fastener is caused by the application of a twisting force applied at a distance from the fastener's axis of rotation. This twisting force results from tightening tools, such as wrenches or sockets, which create a rotational motion. The amount of torque is influenced by factors like the magnitude of the applied force, the length of the lever arm, and the friction present between the fastener and the materials it connects. Proper torque is essential for achieving the desired clamping force and ensuring the integrity of the joint.

Fluid statics and fluid dynamics were significantly advanced by several key figures throughout history. Archimedes, in ancient Greece, is often credited with foundational work in fluid statics, particularly with his principle of buoyancy. In the 17th century, scientists like Blaise Pascal and Daniel Bernoulli made major contributions to fluid dynamics, with Bernoulli's principle being a cornerstone in understanding fluid behavior. Their collective work laid the groundwork for modern fluid mechanics.

The torque specification for a Chevy torque converter typically ranges from 30 to 50 foot-pounds, depending on the specific model and year of the vehicle. It’s essential to consult the service manual for the particular Chevy model you’re working on, as specifications can vary. Proper torque is critical to ensure the torque converter is securely mounted and functions correctly. Always use a torque wrench for accurate measurement.

When the probe is already on its way and we can neglect the station's gravitational attraction, it won't need any more propulsion and will continue to move as it started.

This is due to Newton's first law: any object will stay at rest or continue its movement at constant velocity when no unbalanced forces are acting on it.

Deep space, as you describe, virtually satisfies this conditions, as any gravitational influencing bodies are so far away, their gravitational pull is negligible. Also, in a very deep space, away from stars, dust and gases clouds, there wouldn't even be much frictional force.

The weight of an object is its mass times the acceleration of gravity.

The acceleration of gravity at the center of the Earth is zero.

A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.

It's also called "hypoid oil" because it's used in hypoid geartrains. It's a very thick, somewhat sticky oil used in things like manual transmissions.

It's based on the air pressure measurement of the environment. Before it starts to rain pressure dramatically drops. That's particularly why some people have headaches before rains.

To jump, you need the force of your leg muscles pushing off of the floor to move you into the air. Without bending your knees, you can't use your leg muscles.

The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary.

The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room; see link: "Speed of Sound in Air and the effective Temperature".

Wood or dry grass have much higher friction coefficient than mud so the tires won't slip on them so easily.

As you walk down the stairs, you apply a force to keep yourself from falling down the stairs. The force is in the upward direction, but your movement is in the downward direction. If the force is in the opposite direction of motion, work done by the force is negative. Gravitational force, because it pulls down, does positive work.

It could be considered a wedge since it forces something apart as it advances. If you were attempting to categorize it as one of several simple machines in an academic setting it would be a wedge.

Equilibrium occurs whenever the net force on an object is 0.

A basic example is a person standing up. This person is at equilibrium because the net force on them is 0, and they are not accelerating. The force of gravity is pulling them down at 9.81 meters per second, but the surface that they are standing upon is pushing back up at 9.81 meters per second as well (This is called the "normal" force). Therefore, the two forces cancel each other out and the net force is 0.

The same would be true in a situation where two people are pushing with equal force in opposite directions on a box.

The law of conservation of energy was never found to be violated. The relevance for a machine is that a machine can not produce more energy than is put into the machine.

Analog transducers convert the input quantity into an analog output which is a continuous function of time. E.g.-L.V.D.T,Thermocouple, Strain guage

Digital transducers convert the input quantity into an electrical output which is in the form of pulses.

No a cart is a vehicle. Friction is resistance to a change in acceleration.

You would experience fluid friction and rolling friction, and since you are not likely to be completely submerged, air resistance.

This is a very good question and as such requires a very good answer. If the person is 5 foot 6 inches tall and they fall over they will be able to break their fall if they grab something as long as they catch something within 2.34 feet of their initial leaning into the fall. If they've been drinking then it may be a shorter amount of distance. If they're falling asleep then maybe even shorter still. It's important to not drink and fall asleep while standing as you never know when you might fall and need to grab something handy. If you can only grab something smaller such as children or grandparents then it may be an even bigger problem. If you're in a wedding and a wedding cake is nearby be sure not to be near as too many accidents have been documented when people fall near them. They either should pass laws about placing Wedding cakes too close to grooms or pass laws on allowing camera's at weddings which document these cases. If curtains are available to grab then the fall incline has been known to be able to be extended up to 2.76 feet. Small children have been shown to be unreliable in some of these circumstances due to their continued interest in the common activity often called playing.

We have to assume that the question is saying that the 200-N is the minimum force required to cause the plank to just barely rotate. When the rotation begins, we have a simple lever on one brick, and we can forget about the second brick. The child is standing on the lever's short arm. The child's first moment is (200N x 0.5m), and the first moment of the short piece of plank is (0.1W x 0.25m). The sum of moments on the short side is (100 + 0.025W). On the long side, the moment is (0.9W x 2.25) = (2.025W) . The moments on both sides are equal ===> (100 + 0.025W) = (2.025W) 100 = 2W ===> W = 50N

Scalars are not always negative. The word scalar means that a value behaves like the numbers we are familiar with. You just add and subtract them. These are different than vectors, where you need to break them into scalars in order to add them first.

No. Diffraction is not a wave; it is something that HAPPENS to waves; to all sorts of waves.
