For a bronze alloy, the stress at which plastic deformation begins is 267 mpa and the modulus of elasticity is 115 gpa.
(a) what is the maximum load (in n) that may be applied to a specimen having a cross-sectional area of 341 mm2 without plastic deformation? in (n)
(b) if the original specimen length is 169 mm, what is the maximum length (in mm) to which it may be stretched without causing plastic deformation? in mm

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)
