Ventilation HVAC Hygiene Exhaust GreaseGrease accumulation in exhaust ducts is a re danger Therefore ducts need to cleaned regularly – as per how many hours kitchen is used per day – in Steering Systems. Manual steering system – relies solely on the driver to provide steering force. Power assist – (power steering) – uses hydraulic or electric power to help the driver apply steering force. Addendum circle. : . a . circle touching the outermost points of the teeth of a circular gear . wheel.. Addendum circle. Dedendum circle . : . the circle touching the bottom of the spaces between the teeth of a gear wheel.. Gear system or box is a transmission system of power which is used in all type of vehicles. Gear is a speed and torque changing device used between the engine and the driving wheels. It is a simple machine used to generate more speed or power or send the power of machine in another direction. Wednesday, December 12. th. , 2:30-3:30 EST. Questions?
