Lоng Questiоn 2 (Tоtаl 20 points) Problem Stаtement Here is а rough model of a car with a passenger in it. The car + wheel+ tire + suspension is shown by spring-mass-damper system ( kc, Mc, cc). The passenger + seat system is modelled by a spring-mass-damper system ( kp, Mp, cp ) on top of the car system. The car moves on a road whose height is given by a variable u measured from a fixed reference height (ground). Your Objective Write all the equations and process to find the TF from U to Yp. No need to actually find it. HintsYou can ignore gravity and spring-rest-lengths due to variable definitions from equilibrium that we usually do. u is the height of road w.r.t. to a fixed ground. It’s an absolute coordinate. yc is the height of the car-mass relative to the road. It’s a relative coordinate. yp is the height of the passenger-mass relative to the car. It’s a relative coordinate.Hence, if at some random instant in time, u=1, yc = 2 and yp =3, then the road is up by 1, the car has moved up in total by 1+2=3, and the passenger has moved up in total by 1+2+3=6, from their original equilibrium positions. Procedure Work neatly on paper showing FBD, all equations, algebra, etc.Neat + clean + organized = extra credit! Then show your papers to camera for academic integrity. Then type things below. After exam, submit your work as a pdf on canvas. You may get some partial credit if it applies. Point Distribution- FBDs of passenger and car: ~3 points. - All the equations showing spring & damper forces and accelerations: ~14 points- Clear specific, no-bullshit explanations of steps needed to get to the final TF, e.g., solve this variable from this equation and plug into that equation, and rearrange this into that format, etc.: ~ 3pointsNo essays, just ~1-2 lines is all you need. Essays = time waste and fillers. Type Below (Very Important) Type final Newton's law equation of passenger.Only use usual symbols like kc, Mc, cc, kp, Mp, cp, U, Yc , Yp , s / dots (derivatives) etc. Type final Newton's law equation of car. Only use usual symbols like kc, Mc, cc, kp, Mp, cp, U, Yc , Yp , s / dots (derivatives) etc. Type ~1-2 line of clear and specific steps needed to get to the final TF from U to Yp, e.g., solve this variable from this equation and plug into that equation, and rearrange this into that format, etc. No need to show any algebra or the final TF or FBDs. FBDs go in the papers you'll submit after exam.
Lоng Questiоn 1 (Tоtаl 20 points) Problem StаtementHere is а very simplistic model of a (rear-wheel drive) electric car run by a dc motor.The armature resistance of the motor is R, the armature inductance is about 0, the motor torque and back emf constants are both K , and the rotational inertia of the motor’s armature is 0. The total mass of the car is M and the car moves in the air with linear air drag cv . When you apply the voltage V to the motor, it provides a motor torque Tm and motor angular speed wm to the input of the transmission. The transmission then delivers the torque Tw and speed ww to the rear wheels. The gear ratio of the (very light & frictionless) transmission is G . Assume the wheels too are very light and have radius r, and don’t slip on the road. Your ObjectiveFind the transfer function from the motor voltage V to the car speed v. HintsSpeed v of the car, assuming no slipping of the wheel, is related to angular speed of the ww and radius of the wheels as: v=rww.In going from the motor to the wheels through the transmission, while the torque increases by a factor of G (assuming no friction and massless gears), the angular speed decreases by the same factor G.

Type all the equations on electrical, motor, transmission, and mechanical side needed to get to this TF.Only use usual symbols/variables like: R, K, I, V, Vb, Tm, wm, Tw, ww, G, v, M, r, c, f, F etc. No need to type algebra steps needed to get from equations to TF.
