Where the above condition exists, the angular velocity of the connecting link CB is 7 rad/s.

To determine the velocity of the block at C and the angular velocity of the connecting link CB, we need to use the velocity analysis of the mechanism. The given values of angular velocity vab, and the positions of U and F, can be used to calculate the velocities of the other links and points in the mechanism.

Assuming the mechanism is in 2D, we can use the velocity analysis equation:

v = r x w

where v is the velocity of the point, r is the position vector of the point relative to the origin, and w is the angular velocity vector of the link. We can also use the relative velocity equation:

vB = vA + wAB x rB/A

where vB is the velocity of point B, vA is the velocity of point A, wAB is the angular velocity vector of link AB, and rB/A is the position vector of point B relative to point A.

At the instant u = 45° and f = 30°, we can draw the mechanism in that position and calculate the required velocities:

Velocity of point C:

We can use the relative velocity equation to find the velocity of point C:

vC = vB + wCB x rC/B

The position vector rC/B can be calculated as rC/B = (-0.2i - 0.2j) m, and the angular velocity vector wCB is perpendicular to the link CB and has a magnitude of vAB/|CB| = 3/0.3 = 10 rad/s.

Therefore, wCB = 10k, and vB = 3(0.3i) = 0.9i m/s (because the distance CB is fixed). Thus,

vC = 0.9i + 10(-0.2i - 0.2j) = -2.1i - 2j m/s

So, the velocity of the block at C is -2.1i - 2j m/s.

Angular velocity of link CB:

We can use the angular velocity equation:

wCB = wAB + wBC

where wAB = 3k rad/s, and wBC is perpendicular to the link BC and has a magnitude of vCB/|BC|.

Since vCB is perpendicular to the link BC, we can use the velocity components in the i and j directions to find vCB. We know that vC = vCB + wBC x rB/C, and since rB/C = (0.3i - 0.1j) m, we have:

vCB = vC - wBC x rB/C = -2.1i - 2j + wBC(-0.3j - 0.1i)

Since the velocity is perpendicular to the link BC, we know that the i component of vCB must be zero, so we can solve for wBC:

0 = -2.1 - 0.3wBC

wBC = 7 rad/s

So, the angular velocity of the connecting link CB is 7 rad/s.

On a 20-degree inclined plane using the polar plot angle definition, a stationary object will have a normal pointing along an elevation angle of 20 degrees.

According to the polar angle definition, the angle of inclination is calculated from the horizontal, with 0 degrees being parallel to the horizontal and 90 degrees being perpendicular to the horizontal. As a result, on a 20-degree inclined plane, the angle of inclination is measured from the horizontal plane, with 20 degrees being the angle of inclination.Therefore, the normal force, which is perpendicular to the plane, will point along an elevation angle of 20 degrees. The normal force, on the other hand, is equivalent in magnitude to the weight of the stationary object on the inclined plane, which is given by the formula:weight of stationary object = mass of object x gravitational accelerationwhere the mass of the object and gravitational acceleration are constant values determined by the properties of the object and the location of the inclined plane.

Finally, it is critical to emphasize that the polar angle definition is only relevant when dealing with two-dimensional systems. When dealing with three-dimensional systems, the angle of inclination is calculated differently and is referred to as the inclination angle, which is the angle between the plane and the horizontal plane.

The design requirements that led to the combination of ceramic tiles and aluminium materials for the hull of shuttle space are; discussed below.

The space shuttle experiences extreme temperatures during re-entry into the earths atmosphere. Thus, as a result, a thermal protection system must be provided to help prevent damage of the shuttle structure.

Therefore, the skin must be made up of material that has an exceptionally low thermal conductivity and also the material must be able to be firmly attached to the skin and also be able to be easily repaired in case of any damage.

Secondly, the tiles used on the space shuttle will have to be composed of silica fibers that are bonded together to generate a ceramic of low density. The thermal conductivity of the ceramic would have to be low such that if you touch one end while the other is very hot, you will not feel the hotness.

Now, the tiles will be attached to the shuttle skin with the aid of a rubbery polymer which ensures that the forces don't break the tile loose which will then expose the underlying skin to high temperatures.

The way that chain branching affects a) degree of crystallinity, b) strength, and c) elongation of polyethylene is given below.

Polyethylene is a type of polymer that is made up of long chains of repeating units of ethylene. The properties of polyethylene can be influenced by the size and shape of these chains, as well as the way that the chains are organized within the polymer. One way to alter the properties of polyethylene is to introduce chain branching into the polymer.

a) Degree of crystallinity: Chain branching can have a significant effect on the degree of crystallinity of polyethylene. Crystallinity refers to the degree to which the polymer molecules are organized in a regular, repeating pattern. In general, the more crystalline a polymer is, the stronger and stiffer it will be. In unbranched polyethylene, the molecules are able to pack together tightly, which leads to a high degree of crystallinity.

b) Strength: The strength of a polymer is related to its degree of crystallinity. As a result, the strength of polyethylene will typically be lower when chain branching is present. This is because the chain branches disrupt the regular, repeating pattern of the polymer molecules, making it more difficult for the polymer to resist deformation.

c) Elongation: Elongation refers to the ability of a polymer to stretch or elongate before breaking. Polymers that are more crystalline tend to be less elongation, while polymers that are less crystalline tend to be more elongation. Therefore, when chain branching is present in polyethylene, the polymer will tend to be more elongation. This is because the chain branches disrupt the regular, repeating pattern of the polymer molecules, making it easier for the polymer to stretch.

Therefore, note that properties of Polyethylene can vary depending on the type of polyethylene and the way the polymerization process is carried out, thus the effects of chain branching on it's properties may be different depending on the context.

The compressibility of a fluid can be defined as a measure of the change in volume (density) with respect to the amount of pressure applied to the fluid. Thus, as the pressure of a compressible fluid increases, both its viscosity and density increases.

Some examples of compressible fluids are vapors, gases, air etc.

Additionally, the compressibility of fluids plays a significant role in the field of science such as in aerodynamics, fluid mechanics, thermodynamics etc.

Viscosity can be defined as a quantity expressing the magnitude of internal friction that restricts the ease of flow between parallel layers at some distance apart having unit speed relative to each other.

The minimum clock period for this CPU should be at least 345 ps.

To determine the latencies and clock period requirements for different instructions in the given exercise, we will consider the provided values for the logic block latencies.

4.7.1:

The latency of an R-type instruction refers to the time required for the instruction to complete its execution. In this case, the R-type instruction consists of register read, ALU operation, and register write. From the given values, we can determine the total latency by summing the latencies of the logic blocks involved:

Latency = Register Read + ALU Adder + Register Write

Latency = 150 ps + 25 ps + 150 ps

Latency = 325 ps

Therefore, the clock period should be at least 325 ps to ensure the correct execution of an R-type instruction.

4.7.2:

The latency of ld (load) instruction represents the time required to complete the load operation, which involves register read, sign extension, ALU operation, and register write. Adding up the latencies of the involved logic blocks:

Latency = Register Read + Sign Extend + ALU Adder + Register Write

Latency = 150 ps + 20 ps + 25 ps + 150 ps

Latency = 345 ps

Thus, the clock period should be at least 345 ps for the correct execution of the ld instruction.

4.7.3:

Similar to the ld instruction, the sd (store) instruction involves register read, sign extension, ALU operation, and register write. Adding up the latencies:

Latency = Register Read + Sign Extend + ALU Adder + Register Write

Latency = 150 ps + 20 ps + 25 ps + 150 ps

Latency = 345 ps

The clock period should be at least 345 ps for the correct execution of the sd instruction.

4.7.4:

The latency of beq (branch equal) instruction involves register read, ALU operation, and control logic. Summing up the latencies:

Latency = Register Read + ALU Adder + Control

Latency = 150 ps + 25 ps + 50 ps

Latency = 225 ps

A clock period of at least 225 ps is required for the correct execution of the beq instruction.

4.7.5:

The I-type instruction refers to the load and store instructions (ld and sd). Since we have already determined their latencies in previous questions:

I-type Instruction Latency = Latency of ld or sd = 345 ps

4.7.6:

The minimum clock period for this CPU would be equal to the highest latency among all the instructions. From the previous calculations, the highest latency is 345 ps.

Therefore, the minimum clock period for this CPU should be at least 345 ps.

kinetic friction static friction

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.
