The shaft with connected plate is rotating with angular velocity of 10 rad/s and 1-10 angular acceleration of 2 rad/s^2. for point c located on the corner of the plate, determine the velocity and acceleration vectors in cartesian vector form at the instant shown.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
