Film used to be everything, and the optical illusion of movement by projecting frames of film via light is monumentally important to the advancement of visual entertainment. In this video Bill, engineerguy, tears apart a film projector to reveal the amazing mechanisms used in the pre-digital age to trick the mind into seeing a moving image.

He uses high speed photography and animations to show how the projector moves the film intermittently, how a shutter strategically blocks light as the film moves, and how the photo sensor reads the sound. If you ever wondered exactly how all the individual pieces work together and sync up, then this is for you. Heck, even if you’re just a fan of “How It’s Made,” you’ll love this.

Reinforced Concrete with FRP Bars: Mechanics and Design (Repost)

Reinforced Concrete with FRP Bars: Mechanics and Design By Antonio Nanni
2014 | 418 Pages | ISBN: 0415778824 | PDF | 17 MB

Corrosion-resistant, electromagnetic transparent and lightweight fiber-reinforced polymers (FRPs) are accepted as valid alternatives to steel in concrete reinforcement. Reinforced Concrete with FRP Bars: Mechanics and Design, a technical guide based on the authors’ more than 30 years of collective experience, provides principles, algorithms, and practical examples.

Well-illustrated with case studies on flexural and column-type members, the book covers internal, non-prestressed FRP reinforcement. It assumes some familiarity with reinforced concrete, and excludes prestressing and near-surface mounted reinforcement applications. The text discusses FRP materials properties, and addresses testing and quality control, durability, and serviceability. It provides a historical overview, and emphasizes the ACI technical literature along with other research worldwide.
Includes an explanation of the key physical mechanical properties of FRP bars and their production methods Provides algorithms that govern design and detailing, including a new formulation for the use of FRP bars in columns Offers a justification for the development of strength reduction factors based on reliability considerations Uses a two –story building solved in Mathcad® that can become a template for real projects
This book is mainly intended for practitioners and focuses on the fundamentals of performance and design of concrete members with FRP reinforcement and reinforcement detailing. Graduate students and researchers can use it as a valuable resource.

Antonio Nanni is a professor at the University of Miami and the University of Naples Federico II. Antonio De Luca and Hany Zadeh are consultant design engineers.
