Statics

A position, by itself, has no dimension.

" If a number of forces acting at a point be represented in magnitude ad direction by the sides of a polygon in order, then the resultant of all these forces may be represented in magnitude and direction by the closing side of the polygon taken in opposite order "

(a+b)/2 = 25

(a*b)^0.5 = 20

a = 400/b

b^2-50b+400=0

b=40, b=15

a=15, a=40

One difference between dynamic torque and static torque is the level of difficulty to measure. Static torque is each to measure, while dynamic torque is not. This is because it requires a transfer of an electric or magnetic effect.

Potential energy can be calculated by the equation U ( which is the potential energy) = mgh, where m is hte mass, g is gravity, and h is the height of the object above the point where h=0 (often the ground). So, as long as h does not equal zero (imagine the man sandin on a cliff above sea leve, which is h=0) then he will have potential energy.

Lead is a softer metal compared to copper, which makes it easier to rotate due to its lower hardness. The difference in hardness between the two metals affects their ability to deform under the rotational forces, leading to the lead sphere being easier to rotate.

In a concurrent force system, all forces pass through a common point. In the previous case involving the application of two forces to a body, it was necessary for them to be colinear, opposite in direction, and equal in magnitude for the body to be in equilibrium. If three forces are applied to a body, as shown in the figure, they must pass through a common point (O), or else the condition, SMo= 0, will not be satisfied and the body will rotate because of unbalanced moment. Moreover, the magnitudes of the forces must be such that the force equilibrium equations,

SFx= 0, SFy= 0, are satisfied.

No, it is nominal.

When stones are stricken against one another, then there are chances of transfer of electrons from one to the other. So positive in one and negative charges in the other are produced. Now comes a chance to have an electrical discharge between them which leads to produce sparks in air.

Milligrams can't be converted to milliliters. Milligrams measure mass, while milliliters measure volume.

When the alternative hypothesis is non-directional, we use a two-tailed test.

Example:

H0: mean = 50

Ha : mean not equal to 50

Here is a directional hypothesis that would use a one-tailed test.

H0: mean = 40

Ha : mean > 40

or

H0: mean = 40

Ha: mean < 40

There are a great number of advantages and disadvantages of Arithmetic mean. One disadvantages is that it is not accurate.

Weight is measured on a ratio level of measurement. This is because it has a true zero point (indicating no weight) and allows for meaningful comparisons between values, such as determining how many times heavier one object is than another. Additionally, both differences and ratios can be calculated with weight measurements, making it suitable for various statistical analyses.

The dimensions of angular momentum are usually represented as mass multiplied by velocity multiplied by distance, which is equivalent to kilogram meters squared per second (kg m^2/s). It is a measure of the rotational motion of an object.

The significance of the proportionality of the elastic limit lies in its role in material mechanics, where it defines the maximum extent to which a material can deform elastically under stress. Beyond this limit, materials begin to exhibit plastic deformation, meaning they won't return to their original shape. Understanding this concept is essential for engineers and designers to ensure that structures can withstand applied forces without permanent deformation, thereby ensuring safety and performance. It also aids in selecting appropriate materials for specific applications based on their elastic properties.

[Electrostatics generated by what is called triboelectric effect, occur all the time around us every day. We just don't notice most of the time. Anyone taking a piece of pastic wrap off a roll is generating static electic charges; that individual is actually separating charges to create voltage. In that case, the voltages are small, but in other cases, the voltages can become significant - and dangerous in the exteme!] The discharge of electrostatic buildup can be a major problem around volatile chemicals such as gasoline or other fuels. The spark created by the equalization of charge can ignite them. Worse, if vapors are present in a sufficient concentration, the combustion will be so rapid that there will actually be an explosion! Even dense dust clouds can combust when exposed to electrostatic discharge, as any workers around grain elevators are constantly trained to be aware of. One example involves fueling cars at a gas station in winter. Passengers who leave the vehicle may deposit a strong charge on the vehicle, and if the metal gas nozzle then touches the car body, the spark can ignite the fuel vapors. During refuelling of aeroplanes, friction between the fuel and the hose causes static electricity. A wire can be used to discharge it safely, much like a lightning conductor, and the use of this grounding wire is mandated on fuel trucks at airports.

Also there are two safety hazards involving electrostatic generators used in science classrooms.

The first involves heart fibrillation caused by capacitors or "Leyden Jars" being discharged across a victim's chest. If a VandeGraaff or Wimshurst machine is used to charge up a Leyden Jar with capacitance larger than about 100 picofarads, and if the victim touches the terminals with two opposite hands (so the current path is through arms and chest,) the large current can trigger a heart attack. This happens rarely, but the danger is always there.

The second involves heart fibrillation caused by discharging of a "human chain." If a large group of students holds hands while one student touches an electrostatic generator, the chain of students becomes charged. If one student then touches a grounded water pipe or electric outlet, the current through that student's chest can be more than enough to trigger a heart attack.

Also, there are solid state (semiconductor) devices, such as CMOS components, that are particularly vulnerable to electrostatic discharge. This can involve humans in that any persons with implanted medical devices which extend through the skin (such as Cochlear Implants) and which use CMOS electronic components, might destroy their expensive devices by causing an arc from their body to a metal object. 2. One of the most hazardous places electrostatic charge can be is in the fireworks, munition factories and solid space rocket booster factories. Before the final products are produced there is mixing of firing explosives in motors for fireworks rockets. Gun powder can also be ignited by a spark from an electrostatic discharge. These factories are extremely dangerous in that there is a large amount of these explosives stored on location.
