1. Sewing is a craft that involves stitching fabrics together either with a needle and thread by hand or with a machine. 2. All day long every day without thinking about it you are looking at things that have been sewn. Clothing is one of the most basic needs of human beings and clothing needs to be sewn. There are countless other things that you use or see each day that were sewn. Shoes‚ bags‚ curtains‚ umbrellas‚ stuffed toys‚ and upholstered furniture are all made by sewing. People have

FENDER MARINE CYLINDRICAL FENDERS (Ship Fenders). Cylindrical fenders are commonly used fenders recommended for all types of application to ensure a safe and linear berthing for the different kind of vessels. Cylindrical fenders are an economical solution to protect most of the berthing structures and offer much ease for installation. With 50% design compressive deflection‚ this kind of rubber fender can effectively buffer the collision between docks and ships. FENDER MARINE Cylindrical

HURRICANE SANDY Hurricane Sandy was a tropical cyclone that devastated portions of the Caribbean‚ Mid-Atlantic and Northeastern United States in late October 2012. The eighteenth named storm and tenth hurricane of the 2012 Atlantic hurricane season‚ Sandy was the largest Atlantic hurricane on record‚ as measured by diameter‚ with winds spanning 1‚100 miles. Sandy is estimated in early calculations to have caused damage of at least $20 billion. Preliminary estimates of losses that include business

(essentially‚ the length of the jib). D = Distance from the hinge axis to the face of the column. dc = Column depth. tf = Column flange thickness. For an HSS column‚ torsion manifests itself as a shear stress in the walls (fs = T/2bht) and thus is not directly additive to axial and bending stresses. This shear stress should be evaluated separately by the designer and‚ if significant‚ should be checked along with bending

In physics‚ elasticity is the tendency of solid materials to return to their original shape after being deformed. Solid objects will deform when forces are applied on them. If the material is elastic‚ the object will return to its initial shape and size when these forces are removed. The physical reasons for elastic behavior can be quite different for different materials. In metals‚ the atomic lattice changes size and shape when forces are applied (energy is added to the system). When forces are

time. A major factor in the particular devastation and lethality of a wave of molasses is the fact that molasses is a non-newtonian fluid. When something behaves as a non-newtonian fluid‚ it flows as a liquid when low shear force is applied but becomes similar to a solid when high shear force is applied such as when impacting another object. (Jabr) This means that when the wave of molasses hit an object‚ it was able to transfer a larger amount of its kinetic energy into that object. When the molasses
