HWHAT kinds of bridges are there? • SUSPENSION BRIDGES!!! • Use cables hung from towers to support the road and are attached to cofferdams • AN EXAMPLE!!! The Golden Gate Bridge in San Francisco
TRUSS BRIDGES!!! • Uses connected components that can be stressed from tension and compression. • EXAMPLE!!! This one.
ARCH BRIDGES!!! • Uses an arch shape that thrusts its weight into abutments at either side of the bridge. • EXAMPLE!!!
BEEEAAAMMM BRIDGES!!! • Uses horizontal beams supported by piers • EXXXAMPLE!!!
BRIDGES IN HISTORY!!! • BRIDGE - TO - TERIBITHIA!!! • A – BRIDGE – TOO – FAR!!!
EPIC - FAAAIIIILS!!!!!!!!! • TACOMA NARROWS!!! • STATUS = FAIL!!! • TYPE = FAIL/SUSPENSION!!! • U.S. – DOGGY GOT IT GOOD!!!
RAIL BRIDGE, NEAR ST. JOHN’S STATION • STATUS = TRAIN FAIL!!! • U.K. - TRAINS WENT BOOM!!! • TYPE = NOT GOOD ENOUGH!!! • PICTURE – N/A • DEATH TOLL = 100 +
CHHINCHU!!! • STATUS = FAIL-TASTIC!!! (TOO MANY PEOPLE PARTYING) • TYPE = SUSPENSION • NEPAL – 19 D.O.A., 15 MISSING???!!!
BRIDGES LEFT UNBURNED!!! • GOLDEN GATE BRIDGE – SAN FRANCISCO!!! • See picture in slide 2 • SYDNEY HARBOR BRIDGE – SYDNEY!!! • LUPU BRIDGE – SHANGHAI!!!
STRESS!!! tension, strain, and compression • Stress – the force applied per unit of area • Strain - is perpendicular to that of the force applied to an object, and defines how much an object is deformed compared to its original status • Tension – Acts to lengthen an object • Compression – Acts to shorten an object
