Machinery: A combine costs $1.55 per acre, what is the cost to operate the combine for a rectangular field measuring 2147 meters by 0.85 miles? 1 acre = 43,560 square feet 1 hectare = 2.47 acres 1 acre = 0.4045 Hectares Area of Rectangle = length x width 1 mile = 5,280 feet 1 foot = 0.3048 meter

Electrical: 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 W = V x A (10 x 150 Watts) + (3 x 300 Watts) + (12 x 40 Watts) = 2880 watts 2880 watts = 120-Volt x Amps 2880 watts/120-volts= Amps = 24 Amps

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

Structural: Steel angle iron is sold for $1.79 per linear foot, steel tubing is sold for $2.11 per linear foot, and rebar is sold for 56 cents per linear foot. 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? 112' x $ 1.79 / ft = $ 200.48 95' x $ 2.11 / ft = $ 200.45 12 x 20' x $ 0.56 / ft = $ 134.40 Total = $ 535.33 $ 535.33 x 1.0667 tax = $ 571.036511

Environmental: 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? There are five spaces (equal changes in elevation) between 2900 feet and 3000 feet. (3000' – 2900') ÷ 5 = 20 ft. Each space between lines represents 20' of elevation change. There are four spaces from 2900' so: (2900') + (4 x 20') = 2980'

Environmental: 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.

Machinery: 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 ____________________.

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

Structural: 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?
