A variety of incandescent lights are all operating on a single 120-volt electrical circuit in a livestock barn. The circuit includes ten 150-watt lights, three 300-watt lights, and twelve 40-watt lights. What is the amperage of the circuit with all of these lights operating?

Total Wattage = Voltage x Amperage

For a naturally aspirated engine, what component mixes air and fuel in the proper ratio for efficient combustion?

If 112 feet of angle iron, 95 feet of tubing, and twelve 20-foot lengths of rebar are purchased, and 6.67% taxes are paid with the purchase, what is the approximate total price for the metal?

Refer to the enlarged view of contour lines (in feet) on the topographic map at the right of the page. What is the elevation of the line marked by the arrow?

Using the foresight rod measurement marked with the arrow in the image provided, what is the elevation of the unknown point? Assume a benchmark elevation of 1,252 feet and a backsight of 2.45. A Philadelphia rod is used.

For a hydraulic cylinder, which dimension determines the output force in psi?

Electrical: Circuit protection devices for motor circuits incorporate a time-delay component to allow for a brief period of overload needed for electric motor ________________.

Which component would not be at fault when troubleshooting the fuel delivery system of a gravity-feed float bowl style carburetor?

For a non-family placement/internship agricultural production SAE, what is the FLSA maximum height that a person under 16 years old may work from using a ladder or scaffold?

Which roof type is the most used for agricultural structures?

What is the soil texture with the highest K factor range?

What is the approximate speed, in miles per hour, for a fertilizer spreader that travels 176 yards in 1 minute and 53.5 seconds?

5,280 ft = 1 mile

Compact Equipment: Each cylinder in a three-cylinder engine has a circumference of 11.6 inches and a piston stroke of 6.5 inches. What is the approximate total displacement of the engine in liters?

Approximately how much torque, in foot-pounds, can this PTO produce?

Torque in foot-pounds = Horsepower x 5252 / RPM

Concrete is poured inside a vertical tube form to construct a pylon. If 1.50 cubic yards of concrete are needed to fill the pylon that is 12 feet 5 inches tall, what is the approximate inside diameter of the pylon in inches?

Information: 1 liter = 61 cubic inches Circumference of a circle = 2 x π x radius

Area of a cylinder bore = π x radius2 π = 3.14 radius = diameter ÷ 2

Displacement of a single cylinder = (length of piston stroke) x (the area of the cylinder bore)

What flood control mechanism serves to contain excess water runoff temporarily to allow the water to slowly drain or evaporate?

A recommendation for a CNC plasma table is to ensure an air pressure of 80 psi for high quality cuts. The air compressor provides 235 psi, what component should be installed to ensure high quality cuts?

When wiring to control the same light from three different locations, what switch combination must be used?

A water supply station used to refill pesticide tanks has a 3-horsepower electrical pump that operates at 120 volts. If the motor is 90 percent efficient and has a 0.8 power factor, what is the approximate amperage of the motor?

horsepower = voltage x amperage x power factor x efficiency / 746 (watts to 1 HP)

Compact Equipment: What does the pictorial represent?

Which construction material would have the highest K-value but the lowest R-value?

What computer software is used to map, model, query, and analyze large quantities of data within a single database according to georeferenced data?
