A battery is a device that converts chemical energy directly to electrical energy. It consists of a number of voltaic cells; each voltaic cell consists of two half cells connected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the electrode to which anions (negatively charged ions) migrate, i.e., the anode or negative electrode; the other half-cell includes electrolyte and the electrode to which cations (positively charged ions) migrate, i.e., the cathode or positive electrode. In the redox reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode. The electrodes do not touch each other but are electrically connected by the electrolyte . Some cells use two half-cells with different electrolytes. A separator between half cells allows io...
A gear train is formed by mounting gears on a frame so that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping; this provides a smooth transmission of rotation from one gear to the next. • A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed • It reduces speed and increases torque • Electric motors are used with the gear systems to reduce the speed and increase the torque Types of gear train § Simple gear train § Compound gear train § Epicyclic gear train § Reverted gear train
Control Arm: A movable lever that fastens the steering knuckle to the frame of the vehicle. Control Arm Busing: This is a sleeve which allows the control arm to move up and down on the frame. Strut Rod: Prevents the control arm from swinging forward and backwards. Ball Joints: A joint that allows the control arm and steering knuckle to move up and down and sideways as well Shock absorbers or Struts: prevents the suspension from bounce after spring compression and extension Stabilizer Bar: Limits body roll of the vehicle during cornering Spring: Supports the weight of the vehicle
