Agricultural Engineering Quiz

A type of drilling rig that utilizes both rotary and percussion methods to drill.

Tillage that covers the entire field, unlike band or strip tillage.

The initial tillage step that loosens the soil, covers plant material, and arranges soil aggregates. Prepares the land for planting.

A drilling rig designed for testing that must be operated at a minimum depth of 30 meters and bore hole diameter of 100 mm.

A tillage operation that moves soil to establish a specific elevation and slope.

Earthmoving operations encompass activities such as loosening, loading, carrying, and unloading soil.

A field operation pattern where the machine turns at the end of each strip.

Tillage operations aimed at reducing soil strength, covering plant materials, and rearranging soil aggregates.

A tool that breaks up compacted soil beneath the surface, primarily used to improve drainage and root growth.

The process of wearing down or scratching materials due to the friction of soil particles.

A lever that connects the pump rod to the pump head, helping to balance the weight of water being lifted.

The metal rod that connects the pump to the lever and moves up and down to pump water.

A type of disc harrow that has two gangs (rows) of discs with one gang offset behind the other.

A series of raised mounds of soil in a field, typically used for planting crops.

An implement used to break up compacted soil at depths sufficient to improve drainage and aeration.

A lever-operated knapsack sprayer should not exceed this pumping rate per minute.

A drilling method that utilizes a rotating drill bit to cut and loosen the soil, creating a hole with the required diameter.

A drilling method where an external weight or the drilling stem itself is repeatedly raised and dropped. The impact of the drill bit on the soil creates the hole.

A secondary tillage implement with long, curved teeth made of spring steel. These teeth are mounted on transverse toolbars and point downwards for good soil penetration.

The allowable wheel slip for maximum efficiency for two-wheel drive tractors working on tilled or soft soil is within a specific range.

The maximum speed limit for a four-wheel tractor on paved roads.

The flow rate of water through the nozzle of a lever-operated knapsack sprayer should be within a specified range. This range is determined at a specific pressure.

A type of drilling rig that uses a combination of rotary and percussion drilling techniques.

This could refer to 'All of the above' but without more context it is unclear. In this case, understanding the different drilling methods is crucial.

A type of agricultural implement used for breaking up soil clods, leveling the soil, and preparing the seedbed.

A type of harrow that has a series of discs that rotate and cut the soil. They are used for breaking up soil clods and incorporating crop residues.

A type of harrow that has sharp, pointed teeth that penetrate the soil. They are used for breaking up hardpan and incorporating fertilizer.

The Philippine Agricultural Engineering Standard (PAES) is a set of guidelines and specifications for agricultural machinery and equipment in the Philippines.

PAES 151:2010 is a specific PAES standard that focuses on agricultural machinery specifications.

This type of field cultivator has its main frame mounted at the front of the tractor. It is used to break up soil clods and prepare the seedbed.

The Philippine Agricultural Engineering Act of 1998 (RA 8559) and the Philippine Agricultural and Biosystems Engineering Act of 2016 (RA 10915) are laws that govern the practice of agricultural engineering in the Philippines.

A component of a power sprayer that regulates the pressure within the system, preventing over-pressurization.

A type of hand pump that draws in water during the backward stroke and discharges water only during the forward stroke.

A type of power sprayer that is mounted on wheels, usually pushed by an operator or towed by a vehicle. The pump can be powered by a motor or an electric engine.

A type of plowing that involves using a lister to create a furrow midway between two previously planted rows.

A plow bottom used for soils with stubble, trash, and stalks. It has less curvature compared to stubble moldboard and can handle heavier residues.

A type of plow bottom known for its long, narrow, and less sloping moldboard. This design allows for complete inversion of the furrow slice with minimum breakage.

A type of tractor operation that involves turning over the soil using a plow with a specialized bottom shape, such as a share, moldboard, or stubble moldboard.

A type of agricultural implement used to create furrows (long, narrow trenches) in the soil. These furrows are used for planting seeds and for irrigation and drainage purposes.

A four-stroke cycle is a type of internal combustion engine cycle that involves four distinct strokes of a piston within a cylinder. These strokes are: intake, compression, power, and exhaust. Each stroke corresponds to one complete movement of the piston either up or down.

The allowable wheel slip for a four-wheel drive tractor at firm soil, according to PAES 118: 2001, is a range between 6% and 10% for maximum efficiency.

A type of engine where combustion of fuel happens inside the cylinder. This is achieved by compressing air to a high temperature that ignites the fuel.

A three-stroke cycle is a type of internal combustion engine cycle that involves three distinct strokes of a piston within a cylinder. Each stroke corresponds to one complete movement of the piston, either up or down.

A field operation pattern where the tractor follows a route with rounded corners, turn strips at corner diagonals, and the machine starts from the back of the furrow. This pattern is designed to minimize soil compaction and improve efficiency.

A type of agricultural implement used to create raised beds or ridges in the soil. These raised beds provide better drainage and aeration for crops.

The maximum speed of operation for a two-wheel tractor, according to PAES 137:2004, is 15 km/h.
