sound: pessure waves produced when an object vibratesat a frequency between 20 Hz and 20000 Hz and there is a material medium that sound can travel through.
Shrinkage Reducing Admixture “product or product residue may explosively Combust…” • Superplasticizer Kills fish and ruins water – never pour down a Drain! • Colloidal Silver “…known to cause birth defects…” • Silver Nitrate Solution A poison, oxidizer, and corrosive!
MODERNISM (1920-1935) -Fragmentation as a reaction against classical patterns, conventions and tradition.It started before WWI, but it wasn't until afterwards that it developed. -Anti-historicist, rejects sequential time (non-cronological), absolute polarities and the division between past and present (simultaneity). -Elitist: a certain level of knowledge is required to understand this movement. -Cultural despair: society expected changes after WWI, but this didn’t happen and they are in chaos and despair, afraid of the unknown (repetitive and nightmarish circumstances). -Moral relativism: each person judges what is moral or not, there is not any absolute value. -It portrays the impact of technology: a mechanical movement will establish a...

Biomechanics: Application of mechanical principles in the study of living organisms. Kinematics: appearance or description of motion, linear kinetics, angular kinematics. Kinetics: Forces that cause motion, linear kinetics, angular kinetics. Statics: mechanics of objects moving at constant velocity. Dynamics: mechanics of objects in accelerated motion(changing) Qualitative: non numeric description based on observ Quantative: numeric description based on data collected
Force: A push or pull applied, Effect that one body has on another, is a vector quantity wit magnitude and direction, and point of application. Produces motion Internal force:act within the object hold together when acted by external forces. External force: Act on an object as... Continue reading "Average velocity pdf" »
Steak Tartar: 1/start to make the sauce by putting the Salt, pepper, and French mustard into the soup plate 2/Add the lemon juice 3/ Combine the ingredients withe a service fork 4/Add a little olive oil 5/Add the Egg yolk and a little more olive oil. Mix well 6/Ensure that the emulsion is Achived 7/Add the dry ingredients and mix well 8/ Add the chopped steak and Fold in the sauce using a service spoon and fork. The sauce should be evenly Distributed trhough the steak. 9/ add a little brandy and mix well 10/Transfer To a cold joint plate and shape with two forks. 11/Garnish with onion rings and Chopped parsley, Anchovy fillets may be chopped and added with the dry Ingredients, or kept whole and used to garnish de finished dish.

Example 2 Find parametric equations for a particle that starts at (0, 3, 0) and moves around a circle as shown
in Figure 17.1.
: Circle of radius 3 in the yz-plane, centered at origin
Solution Since the motion is in the yz-plane, we have x = 0 at all times t. Looking at the yz-plane from the
positive x-direction we see motion around a circle of radius 3 in the clockwise direction. Thus,
x = 0, y= 3cost, z = -3 sint.
Example 3 Describe in words the motion given parametrically by
x = cost, y = sint, z = t.
Solution The particles x- and y-coordinates give circular motion in the xy-plane, while the z-coordinate
increases steadily. Thus, the particle traces out a rising spiral, like a coiled spring. (See Figure 17.2.)
This curve is called a helix.

(V) Voltage: energy per electron provided by the battery. Energy spent by each electron in a Receiver.
(R) Electric Resistance : opposition of a material to the flow of the electric current
(I) Electric current :number of electrons that flow through the conductor in 1 Second
I or KWH (joules)
Generated in power plants
Produced by batteries and solar calls
V and I change with time (50 times in 1 Second)
I and V are constant
Electrons change their direction of movement
Electrons move always in the same direction
