HARD HATS A hard hat is a type of helmet predominantly used in workplace environments‚ such as construction sites‚ to protect the head from injury by falling objects‚ impact with other objects‚ debris‚ bad weather and electric shock. Inside the helmet is a suspension that spreads the helmet’s weight over the top of the head. It also provides a space of approximately 30 mm (1.2 inch) between the helmet’s shell and the wearer’s head so that if an object strikes the shell‚ the impact is less likely

swift moving waters move at an average of 8.5 miles per hour‚ and sweep through the channel 4 times a day‚ making it very difficult to create them. The piers were the deepest ever to be constructed‚ almost doubling the previous record holder‚ the golden gate bridge. To travel across the bridge‚ not only will you need to drive straight for 5939 feet‚ but you will have to pay 3 per axle on your vehicle. For instance‚ 2 axles cost $6‚ 3 axles cost $9‚ 4 axles cost $12‚ 5 axles cost $15‚ and 6 or more

The Gates Christo and Jeanne-Claude are artists who work together and create large-scale environment works. These works are temporary and they are removed from the site where they are installed‚ typically after about two weeks. Christo and Jeanne-Claude choose part of an environment in which to make their art and people then see the whole environment with fresh eyes‚ even after the artwork has been removed‚ for it remains in the memories of people who have viewed the transformed environment.

Startled by the sound of my canine‚ Charlie barking‚ my spoon plunged onto the table with a recognisable metallic clang as it tumbled across the table knocking what was left of my now soggy cornflakes all over the table. “Be quiet!” I shouted as he was likely to be barking at somebody walking down the street‚ but the barking continued. Slightly annoyed now‚ I went into the front room to see what he was barking at‚ when I heard a ‘rap-a tap-tap’ at the door which was followed by Carlie’s immediate

The collapse of the 1940 Tacoma Narrows Bridge stunned everyone‚ especially engineers. How could the most "modern" suspension bridge‚ with the most advanced design‚ suffer catastrophic failure in a relatively light wind? The State of Washington‚ the insurance companies‚ and the United States government appointed boards of experts to investigate the collapse of the Narrows Bridge. The Federal Works Administration (FWA) appointed a 3-member panel of top-ranking engineers: Othmar Amman‚ Dr. Theodore
