Given the unity feedback system of Figure P8.3, make an accurate plot of the root locus for the following: a. Gs Ks2 2s 2 s 1s 2 b. Gs Ks 1s 2 s 1s 2 Also, do the following: Calibrate the gain for at least four points for each case. Also find the breakaway points, the j-axis crossing, and the range of gain for stability for each case. Find the angles of arrival for Part a. [Section: 8.5]
1) What processes shape planetary surfaces a) Impact cratering i) Impacts by asteroids and comets ii) Most cratering happened soon after the solar system formed à Period of Heavy Bombardment iii) Craters are about 10 times wider than objects that made them and 10-20% as deep as they are wide iv) Small craters greatly outnumber large ones v) Ex. Meteor Crater in Arizona b) Volcanism i) Happens when molten rock (magma) finds a path through crack in the lithosphere to the surface ii) Molten rock is called lava after it reaches the surface iii) If lava has a lot of air in it, it becomes more runny iv) If lava has less air in it, it becomes more dense and thick v) Outgassi
