Presentacion informaticaDanielsendinEl documento habla sobre la astronomía y la gravitación. Explica que la astronomía estudia la posición y movimiento de los cuerpos celestes. Describe los primeros modelos cosmológicos como el geocentrismo y el heliocentrismo, y cómo el modelo heliocéntrico situó al sol en el centro del universo. También cubre la ley de gravitación universal de Newton y la teoría de la relatividad general de Einstein sobre cómo la gravedad afecta el movimiento de los planetas.
Intrenet and its usesRaj ParekhThe document provides an overview of the Internet and how it works:
- The Internet is a global network that allows computers to share information electronically. It can be accessed from anywhere through an Internet connection.
- Web pages are identified by URLs and displayed in web browsers like Safari, Internet Explorer, Google Chrome, and Mozilla Firefox. A URL includes the protocol, server, path, and resource name.
- The Internet has grown from ARPANET in the 1960s and key developments like the introduction of email, the World Wide Web, and graphical web browsers. It enables access to information through various services like web pages, email, file transfers, messaging, and voice calls.
CsRaj ParekhThis document discusses various aspects of communication skills, with a focus on pronunciation and voice modulation. It provides tips for proper pronunciation, the importance of pronunciation in communication. It also discusses voice modulation techniques like volume, pitch, pace, emphasis and inflection. The document emphasizes using pauses to allow listeners to absorb information and to replace filler words. Pauses also help speakers organize their thoughts and allow their mind to "catch up" to their speech. Proper pronunciation, modulation, and use of pauses are important for clear communication.
Fuel cells and its typesRaj ParekhThe document discusses fuel cells, including:
1) A fuel cell generates electricity through an electrochemical reaction between a fuel (typically hydrogen) and oxygen, with water and heat as byproducts.
2) Fuel cells have several types but all consist of an anode, cathode, and electrolyte; they operate by separating the fuel from the oxygen to prevent combustion.
3) Applications include stationary power systems, transportation such as fuel cell vehicles and buses, and portable power devices, with each fuel cell type suited to certain uses.
Molten carbonate fuel celltanveer aaliThe document discusses molten carbonate fuel cells (MCFC). [1] MCFCs operate at high temperatures of around 650°C, allowing them to not require noble metal catalysts. [2] They use molten carbonate as the electrolyte and can internally reform fuels like natural gas. [3] MCFCs have advantages such as high efficiency and generating waste heat, but disadvantages include liquid handling challenges and long warmup times.

4 pure bending- Mechanics of Materials - 4th - BeerNhan TranThis chapter discusses pure bending of structural members. Pure bending occurs when equal and opposite couples or bending moments act on a member. The chapter covers bending deformations and strains, stress due to bending calculated using elastic flexure formulas, section properties that influence bending such as moment of inertia, and bending of composite members made of multiple materials. Examples are provided to demonstrate calculating bending stresses in reinforced concrete beams.
TORSION (MECHANICS OF SOLIDS)Er.Navazhushen PatelThis document discusses torsion in circular shafts. It defines torque as the turning force applied to a shaft multiplied by the diameter. The angle of twist is the angle of rotation at the surface of the shaft under an applied torque. Shear stress is induced in the shaft under pure torsion. The maximum torque a shaft can transmit depends on its diameter and the allowable shear stress. Assumptions in torsion theory and the polar moment of inertia are also defined. Several examples calculating shaft dimensions, torque, power, and angle of twist are provided. Shaft couplings and keys are also discussed.
