Question 16 A smooth wire has the form of the cycloid X = c(0+ sin 0), y = 0, z = c(1 − cos (), where c is a positive constant and - ≤ ≤T. The wire is fixed, with the +z-axis pointing vertically upwards. A particle can slide freely on the wire. Let u = = du/dt. The equation of motion for the sin(0/2) and u in terms of u is then particle ·U = 0 u=0 O ü + 2/2/² ) ü + ²/2 u ü + u=0 ²/ü+u = 0 ü+u = 0 Question 17 A smooth wire has the form of the cycloid x = c(0 + sin 0), y = 0, z = c(1 − cos (), where c is a positive constant and -π ≤ 0 ≤ π. The wire is fixed, with the +z-axis pointing vertically upwards. A particle can slide freely on the wire.
