Lab Manual: Study of CNC Laser Cutting Machine
Objective:
To understand the working principle, components, and operation of a CNC laser cutting machine.
Apparatus Required:
CNC laser cutting machine, design software (e.g., CorelDRAW or AutoCAD), material sheet (wood, acrylic, etc.), safety goggles.
Theory:
CNC (Computer Numerical Control) laser cutting is a non-contact thermal process that uses a focused laser beam to cut materials with high precision. The laser melts or vaporizes the material, and
Como tema actual hemos escogido el problema de la vivienda que tenemos en España. Se trata de una situación que afecta a miles de personas, especialmente a jóvenes y familias trabajadoras, y que se ha convertido en uno de los grandes retos sociales de nuestro tiempo. Tal y como sabéis, la última semana ha tenido lugar una manifestación importante relacionada con este tema: la movilización bajo el lema “Canarias tiene un límite”. Una de las principales razones por las que la gente ha
Giovanni Boccaccio nasce nel 1313, probabilmente a Certaldo, vicino Firenze. È figlio illegittimo di Boccaccio di Chellino, un ricco mercante al servizio della potente compagnia bancaria dei Bardi di Firenze. Viene riconosciuto dal padre, compie i primi studi a Firenze e viene avviato alla carriera mercantile e bancaria. Nel 1327, a soli 14 anni, si trasferisce a Napoli con il padre, per seguire le attività bancarie dei Bardi presso la corte angioina. Qui inizia a esercitare il mestiere di mercante
Duran Duran – Rio (1982) Representation: Ethnicity is largely absent or tokenised. The video features a white British band surrounded by exotic, tropical imagery, filmed in locations like Antigua. Women featured are racially ambiguous or white, and largely passive. Key Example: The tropical backdrop is used to enhance the band’s glamour, but the local culture or people are not acknowledged — the setting becomes a backdrop for white luxury. Theory Link: Said’s Orientalism — the exotic is...
1. In Cat’s Dream, Pablo Neruda uncovers the latent soul of ordinary things by meditating on the quiet, mysterious life of a cat. He sees the cat not just as an animal, but as a symbol of peace, grace, and silent wisdom. The poet marvels at the cat’s detachment from the chaos of the human world. By observing its stillness, poise, and independence, he discovers a deeper essence within the mundane. Neruda believes that even simple, everyday creatures possess an inner richness that often goes unnoticed....
1. Investigate the Relationship Between Mass and Weight
What to do step-by-step:
Attach the spring balance or newton meter securely so it hangs vertically. Place the first known mass (e.g., 100 g) on the balance hook. Wait for the reading to stabilize and record the weight (in newtons). Repeat steps 2-3 for several masses (e.g., 200 g, 300 g, 400 g). Plot a graph of weight (N) against mass (kg).
Variables:
Independent: Mass (kg)
Dependent: Weight (N)
Control: Location (keep experiment on Earth, constant
Modern Family – Media Language
monotony style/direct address: Example: Cam talks directly to the camera: “Lily just needs to fit in like any other kid.” How it’s shown: He breaks the fourth wall, sharing private thoughts with the audience. Theory link: According to Barthes’ Enigma Code, this direct address creates mystery and encourages the audience to decode Cam’s true feelings about social acceptance, increasing engagement and emotional connection.
Editing & pace: Example: Rapid
Friends – Episode 1 Media Language Multi-camera sitcom style with laugh track: Example: Scenes set in Central Perk and Monica’s apartment use fixed cameras, with audience laughter cued after jokes like Ross saying “We were on a break!” How it’s shown: The laugh track guides audience response and highlights comedic timing. Theory link: This fits Curran & Seaton’s idea of formulaic sitcom production aimed at mass appeal, using standard genre conventions to maintain audience comfort...
The statement "All contracts are agreements, but all agreements are not contracts" is a fundamental principle in Business Law and is derived from Section 2(h) of the Indian Contract Act, 1872, which states:
“A contract is an agreement enforceable by law.”
Thus, every contract is essentially an agreement, but only those agreements which are enforceable by law become
