The planetary gear system is used in an automatic transmission for an automobile. by locking or releasing certain gears, it has the advantage of operating the car at different speeds. consider the ease where the ring gear r is held fixed, = 0, and the sun gear s is rotating at omega s = 5 rad/s. determine the angular velocity of each of the planet gears p and shaft a.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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?

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.
