The following data is provided for the tran.slationo.L mechanical .sysl.cm considered in Problem 2. 9.

m1 = 5kg m2 = l5kg m3 = 50kg b1 = 500N/m/s b2 = 600N/m/s k1 = 5, OOON /m

= lO,OOON/m Use MATLAB to find the following:

(a) The output response (y) to an input force of 50N

(b) The response to u.n impulse force ·input.

(c) If the values of b1 and b2 weTe vaTiables choose values of b1 and b2 that will Teduce oscillations, give practical settling time, and produce smooth Tesponses.
If the output was the platfoTm displacement x3 , obtain the new matrices C and D.

(a) Find the output response (y) to an input force of 50N

(b) Find the responBe to an impulse force input.

(c) If the values of b1 and b2 were variables choose valv.es of b1 and b2 that will reduce oscillations, and give practical settling tirn.e and sm.ooth Tesponscs.
