Question

Do a diagram that represent arn memass attached horizontaly by a spring of stiffeess constant K to the wall, where the mass has interaction contact with a Viscous iquid in a dumper of viscosity constant C. Furthermore, the mass is forced to vibrate to and external motor of Force Fo ewot that forced the mass to vibrate with its frequency Wo Write the second Newton's law for the system and detne the parameters that you need: Ike 1) the natural frequency etdc 2) Use as solution of the Newtan's equstion:xAe 3) Find a relation between the Amplitube on the Force Fo 4) Explain why two objects that are in the border of Building terrace, when one is hunched with horizontal velocity and other without acy horaontal velocity at all, Nowever both rich the base of the building at the same ting s) What is resonance? 61 find the Amplitude of the Vibration in resonance. 8) Explain how you calculate the "bank angle" or (Angulo de Peralte), if you know the radius of curvature of the path, and the tangential velocity of the auto. Do diagrams that you need to explain. 9) Explain how do you find the curvature radius of a path that is defined by y= 7) What will be the equation of the path of the object in a parabolic movement in other words What is the equation: Yvs X? (Y is the vertical coordinate and X is the horizontal coordinate of the object in the parabolic movement) Explain how do you find the Inertia moment of a bar of length I, mass m. a) b) 10) Find the Inertia with respect to an axis that pass by the Center of mass and Find the moment of Inertia with respect to and axis that pass by one of the extremes of the bar. Do a diagram that represent an memass attached horizontally by a spring of stiffeess constant x to the wall, where the mass has interaction contact with a Viscous iquid in a dumper of viscosity constant C. Furthermore, the mass is forced to vibrate to and external motor of Force Fo ewn that fosced the mass to vibrate with its frequency Wo Write the second Newton's law for the system and detine the parameters that you need tke 1) the natural frequency etc 2) tUse as solution of the Newtan's equstion:x- A e 3) Find a relation between the Amplitate on the Force Fo 4) Explain whby two objects that are in the border of Building terrace, when one is launched with horliontal velocity and other without any horizontal velocity at all, Howewer both rich the tase of the building at the same tine 5) What is resonance? 61 find the Amplitude of the Vibeation in resonance.
