Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it. A weakly damped spring oscillator of mass 0.269 kg is driven by a sinusoidal force at the oscillator\'s resonance frequency of 23.5 Hz. a. )Find the value of the spring constant. (N/m) b.)The amplitude of the driving force is 0.489 N and the amplitude of the oscillator\'s steady-state motion in response to this driving force is 0.853 m. What is the oscillator\'s damping constant? (kg/s)
A parallel-plate capacitor with air dielectric has a plate area of 75cm^2. if the capacitor is fully charged by a 300-v source and can hold a charge of 7.5x10^-9c, what is the distance between the plates
What is the minimum rate of rotation, in revolutions per minute, required for the spheres to contact the cylinder wall?
A cylinder is rolling along the ground without the slipping at 7m/s. It comes to a hill and begins going up. Assuming no losses to friction, how high vertically would it go before it stops.
a typical maximum acceleration for a car is about 8 m/s^2, A sports car traveling at 20m/s accelerates at this rate for 1.25 seconds
