Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The philosophy of engineering is an emerging discipline that considers what engineering is, what engineers do, and how their work affects society, and thus includes aspects of ethics and aesthetics, as well as the ontology, epistemology, etc.

The statement "Forging is a deformation process in which the work is compressed between two dies, using either impact or gradual pressure to form the part" is true because the dies exert pressure on the workpiece, causing it to deform.

Forging is indeed a deformation process in which a workpiece is compressed between two dies to shape it into the desired form. Let's take a closer look at how forging works.

In the forging process, the workpiece, often a heated metal billet or ingot, is positioned between two dies. These dies have specific contours and shapes that correspond to the desired final shape of the forged part. The dies are typically made of hardened steel and are usually mounted in a forging press or hammer.

When the forging process begins, compressive forces are applied to the workpiece by closing or striking the dies together. This pressure causes the material to flow and deform, taking the shape defined by the dies. The applied force can be achieved through impact, where a hammer or similar tool strikes the workpiece, or through gradual pressure exerted by a hydraulic or mechanical press.

The ethanol-aqueous interface typically contains impurities such as surfactants, soluble organic and inorganic compounds, and other contaminants. Impurities such as this can affect the quality and purity of the final product. There are various ways to remove this interface.

One of them is by using a centrifuge. It can be used to physically remove the interface by spinning the mixture at high speeds. This separates the ethanol and aqueous layers, making it easier to eliminate the interface.Another option is to use a decanter. It is a device that separates liquids with different densities. It can be used to remove the ethanol-aqueous interface by gravity separation.The most effective way of eliminating impurities in the ethanol-aqueous interface is through distillation. It separates the impurities from the ethanol, resulting in a pure ethanol product. This is done by heating the mixture to the boiling point of ethanol. The ethanol vapor is then condensed into a separate container, leaving behind the impurities in the original container.There are several ways to eliminate the ethanol-aqueous interface, but the method you choose will depend on the amount and type of impurities present, as well as the desired purity of the final product.

An entry at the end of a linked-based list can be removed with O(n) performance using just the head reference.

In a linked-based implementation of the ADT list with only a head reference, removing an entry at the end of the list has a performance of O(n). This is because to remove the last element, we need to traverse the entire list from the head to the second-to-last node in order to update the reference and remove the last node.

In a linked-based implementation of the ADT list with a tail reference, removing an entry at the beginning of the list has a performance of O(1). Since we have a reference to the tail, we can directly update the head reference to the next node without traversing the entire list.

In a linked-based implementation of the ADT list with a tail reference, removing an entry that is not at the beginning of the list also has a performance of O(1). We can update the references of the neighboring nodes to bypass the node being removed without needing to traverse the entire list.

Overall, the key difference lies in the ability to directly access the head or tail reference, which influences the performance of removing elements in different positions in the list.

Answer:

Explanation:

a. To find the compression of the spring needed to launch the rock horizontally at 35 mph, we can use conservation of energy. The potential energy stored in the compressed spring is equal to the kinetic energy of the rock when it leaves the spring:

1/2 k x^2 = 1/2 m v^2

where k is the spring constant, x is the compression distance, m is the mass of the rock, and v is the velocity of the rock.

Converting the velocity to meters per second:

35 mph = 15.6 m/s

Plugging in the values and solving for x:

1/2 (23,000 N/m) x^2 = 1/2 (13 kg) (15.6 m/s)^2

x = sqrt[(13 kg) (15.6 m/s)^2 / (23,000 N/m)] = 0.263 m

Therefore, the spring must be compressed by 0.263 meters.

b. To find the maximum height the rock will reach when the spring is oriented vertically, we can again use conservation of energy. The potential energy stored in the compressed spring is converted into gravitational potential energy of the rock when it leaves the spring:

1/2 k x^2 = m g h

where g is the acceleration due to gravity and h is the maximum height reached by the rock.

Plugging in the values and solving for h:

1/2 (23,000 N/m) (0.5 m)^2 = (13 kg) (9.8 m/s^2) h

h = (1/2) (23,000 N/m) (0.5 m)^2 / (13 kg) (9.8 m/s^2) = 0.605 m

Therefore, the rock will reach a height of 0.605 meters above the ground.

c. To find the compression distance when the rock is dropped onto the spring from a height of 14 meters, we need to consider both the potential energy of the rock and the energy absorbed by the spring. When the rock hits the spring, it will come to a stop, so all of its initial potential energy will be converted into potential energy stored in the compressed spring:

m g h = 1/2 k x^2

where h is the initial height of the rock and x is the compression distance of the spring.

Plugging in the values and solving for x, we get a quadratic equation:

1/2 (23,000 N/m) x^2 - (13 kg) (9.8 m/s^2) (14 m) = 0

Simplifying and solving for x using the quadratic formula:

x = sqrt[(13 kg) (9.8 m/s^2) (14 m) / (23,000 N/m)] = 0.473 m

Therefore, the spring will compress by 0.473 meters before the rock comes to a stop.
