Assignment Help Mechanical Engineering
Reference no: EM131175079

A 1000 candela light source emits a beam of light. The source is held exactly 4 ft above a moveable surface. The surface can be sloped at angles in 10° intervals in the range of 0° to 90°, measured from horizontal. Determine the luminous intensity, in foot-candles, on the surface at each angle.
