A 225kN test aircraft moving with velocity vo = xo = 25 km/h collides with a rigid barrier at t = 0. As a result of the behaviour of its energy absorbing capabilities, the response of the aircraft to the collision can be simulated by the damped spring- mass oscillator shown with k = 3MN/m and c = 840 kN.s/m. Assume that the mass is moving to the left with a velocity vo = xo = 25 km/h and the spring is unstretched at t = 0 determine the aircraft's deceleration: a) Immediately after it contacts the barrier; b) at t= 0.04s and; c) at t = 0.08s.

For a certain engine having an average speed of 1200 rpm, a flywheel approximated as a solid disc, is required for keeping the fluctuation of speed within 2% about the average speed. The fluctuation of kinetic energy per cycle is found to be 2 kJ. What is the least possible mass of the flywheel if its diameter is not to exceed 1 m?
04- For the system shown in figure below, the mass (m) of 9 kg stretched a spring for a distance of 100 mm. Then, the mass is pulled to an initial displacement of 150 mm with initial velocity = 0 then released. Determine the displacement of the mass at time (t)=0.8 sec due to the mechanical vibration of the system. Use the gravitational acceleration (g) = 10 m/sec2. k Equilibrium position = 100 mm. m = 9 kg c = 100 N.sec/m
A mass of a 2 slug, when attached to a spring, causes an elongation of 2 ft in this spring and then comes to rest in the equilibrium position. Starting at t = 0 an external force equal to f(t) = 8 (sin (4t)) is applied to the system. Find the equation of motion if the surrounding medium offers a damping force equal to 8 times the instantaneous velocity.
3. A mass of 2 kg stretches a spring by m with a force of 10 N. A dashpot is attached that exerts a resistive force of 16 N and the speed is 2 m/sec. At t = 0, the mass is pulled left 1 m and released with a velocity of m/s to the right. Find the displacement function in the form: Ce-pt cos (w;t-a,). What are the systems pseudo-frequency and pseudo-period?

A mass m is attached to both a spring (with given spring constant k) and a dashpot (with given damping constant c). The mass is set in motion with initial position x0 and initial velocity v0. Find the position function x(t) and determine whether the motion is over-damped, critically damped, or under-damped.

The car's corner mass is m₁ = 220 kg and the unsprung mass is m₂ = 16 kg. The suspension spring stiffness is k, = 13 kN/m and the tire stiffness is k = 150 kN/m. The car is traveling with speed V on a sinusoidal road surface with wavelength = 5 m and amplitude A, = 0.010 m. Neglect the suspension damping and use the complex frequency response method to find the steady-state responses of z₁ (t) and z₂ (t) for speeds from V = 5 m/s to V = 30 m/s in 5 m/s increments.

Maximum fluctuation of kinetic energy in an engine has been calculated to be 2600 J. Assuming that the engine runs at an average speed of 200 rpm, the polar mass moment of inertia (in kg.m) of a flywheel to keep the speed fluctuation within ±0.5% of the average speed is
