There are various types of bearings including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction between two surfaces, commonly found in wheels and pulleys.

• Roller bearings use cylindrical rollers to support heavy loads, commonly found in conveyor belts and gearboxes.

• Plain bearings have a sliding surface instead of rolling elements, commonly found in hinges and sliding mechanisms.

The type of gear box is a manual transmission.

• Manual transmissions require the driver to manually shift gears using a clutch pedal and gear shift.

• Common in sports cars and older vehicles.

• Provides more control over the vehicle's performance compared to automatic transmissions.

Deduction in brick wall as per IS code refers to the reduction in dimensions of bricks to account for mortar joints.

• As per IS code, deduction of 10 mm is done in each dimension of brick (length, breadth, height) for mortar joints.

• This deduction is necessary to calculate the actual quantity of bricks required for a wall.

• For example, if a brick has dimensions of 200mm x 100mm x 100mm, after deduction for mortar joints, the effective dimensions would be 190mm x 90mm x 90mm.

• Non-destructive testing methods like ultrasonic testing

• Testing for workability and consistency using slump tests

• Durability testing for resistance to chemicals and weathering

• Quality control through sampling and testing of concrete mixtures
