Understanding Viscosity and Surface Tension in Fluids

Viscosity and Surface Tension

Viscosity and surface tension are fundamental properties of fluids that describe their resistance to flow and their tendency to minimize surface area, respectively.

Surface Tension

Surface tension is the energy required to increase the surface area of a liquid. It arises from the cohesive forces between liquid molecules. These forces cause the liquid to behave as if it has an elastic membrane at its surface.

Liquids with high surface tension tend to form spherical droplets

MODERNISM (1920-1935)

Fragmentation as a reaction against classical patterns, conventions, and tradition. It started before WWI, but it wasn’t until afterward that it developed.

• Anti-historicist: rejects sequential time (non-chronological), 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

Perfect Trusses

What is a Perfect Truss?

A perfect truss is an idealized structure made up of interconnected members (usually straight bars or beams) joined at their ends to form a stable framework. In a perfect truss:

• Members are perfectly rigid and experience only axial forces (tension or compression).
• Joints are frictionless and perfectly pinned, allowing only forces along member lines.

This simplification helps engineers analyze forces and stresses within the truss, leading to efficient designs for

Kinetic

Reference Frame

An oriented straight line in which motion occurs. It presents an origin and an axis.

Position

The distance between the object and the origin of the reference frame.

Displacement

Difference between any two positions. It moves when it changes position regarding the reference frame.

Velocity

Difference between any two positions: incremento de e: incremento de t.

Acceleration

The measurement of the rate at which the velocity of a body varies: incremento de velocidad entre incremento de

The Complete Guide to the Spanish Card Game

Posted by admin on May 30, 2024 in Physics | 0 comments

This card game is played with a Spanish deck of 40 cards.

Number of Players

You can play with 2 players (1 vs. 1) or 4 players (2 vs. 2).

Objective

The first person or team to reach 24 points (or stones) wins. Sometimes, players agree to play to 12 points.

Dealing and the Vira

Each player receives three cards in each of the three rounds (first, second chase, and third). Additionally, a card called the vira is turned face up, which changes the value of two cards: the Jack of the trump suit becomes the
