Statics

In a simple case of lifting a weight using a pulley, there are two ways to do it and two different results.

First, attach a pulley to the ceiling, and a rope to the weight which is on the floor. Run the rope through the pulley. Now we simply pull down on the rope and the weight is lifted up.

In the second case, we attach one end of the rope to the ceiling, the pulley to the weight, and pass the unattached end of the rope through the pulley. Now we have to pull the rope up, and the weight is lifted.

Now let's look at each job and what happens.

In the first case, pull the rope tight without lifting and hold the rope at the top, next to the pulley. If you now pull the rope all the way down to the floor, the weight goes all the way up to the ceiling. Note also that the tension in the rope is equal to the weight being lifted and that there is only one tensioned rope pulling the weight upwards. Passing over the pulley changes the direction of the tension in the rope but doesn't change it's pulling power. Pulling that rope from ceiling to floor is exactly the same as lifting the weight from floor to ceiling.

In the second case, tighten the rope before lifting and hold the rope where it exits the pulley on the weight. Now pull and your hand moves from there to the ceiling - about the same distance (but the other way) as you moved your hand in the other case. However, notice now that the weight is only half way to the ceiling. It is hanging on a loop of rope, one side going to the hook and the other going to your hand. This suggests that the weight is shared by these two parts of the rope and therefore the tension in each piece only needs to be half the weight. Your hand is holding half the weight. The ceiling hook is still holding the other half.

To finish the job, you will have to keep pulling more rope - all the rope which is still there from hook to weight pulley and back to your hand. That's the floor to ceiling distance. In the second case, you pull twice as much rope to finish the job.

And because it takes twice as long, it only needs half the force at any stage.

To calculate the minimum value of a component given a resultant force, first, identify the force's direction and magnitude. Use vector decomposition to break down the resultant force into its components along the desired axes. Then, apply the relevant equations of equilibrium or force balance to find the minimum value of the component, ensuring that the forces satisfy the given conditions. This often involves solving inequalities or equations that relate the components to the resultant force.

If the ice starts at 0 degrees Celsius and vaporization takes place at 100 degrees Celsius, then ... 10 lbs = 4540 grams

Q = 80(4540) + 1(100 - 0)(4540) + 540(4540)

Q = 720(4540) = 3,268,800 calories

Static information refers to data that remains constant or unchanged over time. This type of information does not require frequent updates and is typically used as reference or background data. Examples include company contact information or historical data in a database.

-- During the tumbling cycle, as garments rubbed together, electrons

separated off of one garment and onto another one.

-- That gave one of them a net positive charge, and the other one

a net negative charge.

-- The law is that opposite net charges attract each other.

The condition of tipping friction occurs when an object resting on a surface reaches the point where it is on the verge of tipping over. This condition is influenced by factors such as the shape and weight distribution of the object, the surface it is resting on, and external forces acting on it. It is important to understand tipping friction to prevent accidents and ensure stability of objects.

Static electricity is actually the build-up of electric charge on the surface of an object. This charge is typically caused by the transfer of electrons from one object to another. So, while the electrons themselves may not be moving through a material, the imbalance of charge creates a static electric field.

There have been a lot of claims that this physical feature or that affects intellectual ability, and maths in particular. Some claim that race matters, gender, head size, body size, you name it.

Now, let's ignore things that really can matter, such things as undiagnosed and uncompensated problems with hearing, sight, health in general, and education and upbringing. All the things that can affect your learning and thinking. No one would be surprised if a blow on the head, or chronic lead poisoning messed up your maths or reading or anything else that needed brainwork, would they?

But a lot of studies that have looked at such things as skin colour and so on affect maths scores. The general effect has been that social factors have a greater effect than any of the others. For example, in communities where learning is seen as sissy or geeky, or where "sexy girls have no brains" and so on, children don't want to do well at maths. But apart from that there is too little effect to matter; perhaps none, for all we can tell.

Two of the smartest maths pupils I have known were a very pretty pair of blonde twins. Two other top scorers were red-headed sisters. Another one that springs to mind as being memorable was a brunette, and another had mousy hair. No baldies, I must admit, but you don't find many of them in high school anyway... And that is not even counting kids who dyed their hair!

You want to know who scored best in general? The ones who took pride in doing a good job, who were interested in life and in doing well, who had the guts to face up to a challenge.

They had hair of any colour you can think of, and every texture.

No. The slope would have to be shorter than the height.
