    A uniform 6-m high, 10-m wide (into the page) rectangular gate is hinged at Point A. The right side of the gate is exposed to the atmosphere while the left side is partially covered by 2 different fluids (oil as top layer and water as bottom layer). The free surface of the oil is 1 m below the hinge at Point A. The oil layer (SG = 0.8) is 2-m thick while the water layer is 3-m thick. Assuming the...

    A cosmic ray muon with mass mu = 1.88 x 10-28 kg impacting the Earth's atmosphere slows down in proportion to the amount of matter it passes through. One such particle, initially traveling at 2.50 x 106 m/s in a straight line, decreases in speed to 1.44 x 106 m/s over a distance of 1.28 km. (a) What is the magnitude of the force experienced by the muon? 5.025 Your response differs significantly from the correct answer. Rework your solution...

    c) A 3 m thick clay layer, free to drain from its upper and lower boundaries, has been subjected to a uniform vertical stress increase of 200 kPa. After 1 year the excess pore pressure at the centre of the clay layer is 50 kPa. If the settlement at 1 year is 0.3 m calculate the final settlement of the clay layer.

    1. [12 points] Compelling evidence for the asteroid impact 65 million years ago which triggered the extinction of the dinosaurs was discovery of a thin Iridium-rich clay layer in sediments all around the world. A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...
