KMODDL - Kinematic Models for Design Digital Library

KMODDL - Kinematic Models for Design Digital Library KMODDL is a collection of mechanical models and related resources for teaching the principles of kinematics--the geometry of pure motion. The core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell's Sibley School of Mechanical and Aerospace Engineering. What is Kinematics?
Concrete, as most folks know, is strong under compression but weak under tension, and is commonly strengthened by casting it around, e.g. a grid of steel reinforcing bar (“re-bar”). Glass Fiber Reinforced Concrete is, well, pretty much exactly what it sounds like: concrete reinforced with glass fibers. As in most composite materials, the fiber elements in GFRC can be carefully oriented, or randomly distributed, in the solid matrix. The nice thing about the latter method is that you can just mix the reinforcing fibers into the bulk concrete and don’t have to pre-position them in the mold.

Flexible Stream • Digital Wood Joints

Flexible Stream • Digital Wood Joints Wood Joints are fascinating! They embellish old furniture and wood constructions of ancient Japanese temples alike. Everytime we come across them, we are filled with admiration: Admiration for the skill of the master craftsman, as their creator, but also admiration for the balance between function and beauty, which turns the furniture or temple into a work of art. With the onset of industrialisation, the traditional wood joints have been banned more and more to the background. Manufacturing has to be above all efficient, so there is no more room for traditional wood joints. Or is there?
