The uniform sign has a weight of 1500 lb and is supported by the pipe ab, which has an inner radius of 2.75 in. and an outer radius of 3.00 in. if the face of the sign is subjected to a uniform wind pressure of p = 150 lb> ft2 , determine the state of stress at points c and d. show the results on a differential volume element located at each of these points. neglect the thickness of the sign, and assume that it is supported along the outside edge of the pipe.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
