Damped system under rotating unbalance: a variable- electric motor, having an unbalance, is mounted on an isolator. as the speed of the motor is increased from zero, the amplitudes of vibration of the motor are obse to be 0.55 in. at resonance and 0.15 in. far beyond resonance. find the damping ratio of the isolator.

Fluids at rest possess no flow energy. a)- true b)- false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
