2. Figure 1 shows a sensor consists of a core, an armature and a variable air gap. The core with 3.0 cm depth and 10000 relative permeability has 200 coil turns. On the other hand, the armature is a steel plate of thickness 0.2 cm and has similar relative permeability with the core. Assuming the relative permeability of air is unity and the permeability of free space is equal to 4x x 10-7 H.m, calculate the inductance of the sensor for air gaps of 0 mm and 2 mm. Please write the answers in 3 decimal places. 2.0 cm 1.0 cm 6.0 cm 3.0 cm 1.5 cm Figure I
1- I need answer of all sub-parts questions. Thanks The figure shows a simple model of a motor vehicle that can vibrate in the vertical direction while traveling over a rough road. The road surface varies sinusoidally with an amplitude of 0.01 m and a wavelength of 6 m. The vehicle has a mass of 1007 kg. The suspension system has a total spring constant of 40 kN/m and a damping coefficient of 20 kN.s/m. The vehicle average speed is v = 100 km/hr. The objective is to determine the vehicle steady-state displacement amplitude as well as the respective transmitted force. Calculate the forcing frequency of the pumpy road. Calculate the natural frequency of the vehicle SDOF system. Calculate the damping ratio of the vehicle SDOF.
