Second picture is answer to the same problem just different numbers. Hope it helps "An automobile, weighing 1100lb empty and 3000 lb fully loaded, vibrates in a vertical direction while traveling at 55 mph on a rough road having asinusoidal waveform with an amplitude Y ft and a period 12 ft. Assuming that the automobile can be modeled as a single-degree-of-freedomsystem with stiffness 30,000 lb/ft and damping ratio zeta=0.15, determine the amplitude ratio of vibration of the automobile when it is (a) empty[A] and (b) fully loaded [B].

(4) You are interviewing for a job as a see-saw designer. In order to get the job, you must solve a design problem involving a meter-stick with two masses hanging on it (see below). The system is to be perfectly balanced, with the pivot point offset from the center of the meter-stick. The mass of the meter-stick is 65.22 g. To get the job, you must find the unknown mass, m, in grams. 1.00 m F- Fplankt FuiOck, t Foluck0 27.0 cm 13.0 cm 65.22g 500. g 0.63096 나.9 massmissing T= 0,63896(1.0) +.500(-27) +.60 (F) = 0 13.16 grams f =1.289N = 0.1316 9.8 (5) The diagrams show a Fn stationary cargo plane Fn1 Fn2 before and after loading it.
