Write the two equations of motion for mass #1 and mass #2 relating X1(s) and X2(s) to the force, F(s) for the mechanical system illustrated in Figure P2.12 on page 101 of your text in matrix form. X1 = 0 X2 = 0 X1 X2 K = 3.0 N/m K = 5.0 N/m f(t) M=2.0kg| fy = 4.0 Ns/m M=1.Okg // frictionless surface

An indexing mechanism of the milling machine uses a gear train shown in figure task 1d. The drive is from gear wheels A and B to the bevel gear wheel D. The following table shows the tooth number on each gear, solve using tabular method.   How many revolutions does D makes for one revolution of A under the following situations: Tabular column (i) If A and B are having the same speed and same direction  (ii) If A and B are having the same speed and opposite direction  (iii) If A is making 80 rpm and B is at rest  (iv) If A is making 80 rpm and B 40 rpm in the same direction.  (v) Also define the term Speed ratio and train value Please with clear words
